Applications

Knowing a metal inside out before making use of it is very crucial. The same goes for copper-nickel alloy. These are alloys of copper and nickel, with or without other elements. In this alloy, the zinc content is not more than 1%. Copper-Nickel alloys are seen to be used widely because of their excellent resistance to seawater corrosion. If you are keen to know more about copper-nickel alloys, stay with us till the end as you will be informed with an in-depth guide.

Mechanical Properties of Copper-Nickel Alloys

A material’s mechanical properties refer to the components that react against applied load. This also states the ability of a material to resist deformation. The following are the mechanical properties of copper-nickel alloys.

The tensile strength is about 372-517 MPA, the elongation at break in metric is 45.0%, talking about shear modulus, it is 57.0 GPA, and elastic modulus is 150 GPA. The machinability of the copper-nickel alloy is about 20%.

Corrosion Resistance of Copper-Nickel Alloys

These types of alloys are counted under corrosion-resistance copper alloys. These are said to be resistant to moisture, alkalis, salt solutions, organic acids, to gases such as oxygen, chlorine, hydrogen chloride, hydrogen fluoride, and carbon dioxide. There is no risk of stress corrosion or cracking with them. The tendency to selective corrosion is pretty small and pitting corrosion is seldom observed. Hence, this is the property that makes it a widely used alloy in many places.

Where Can These Alloys Be Used

Copper-nickel alloys can be used in the following areas:

Desalination units

Hydraulic lines

Fish cages for aquaculture

Heat exchanger

Condensers

Seawater pipework

Offshore firewater systems

Tubes for power plants and ships    

Pumps, valves, sheathings, and fittings for ship hulls

Applications Of Copper-Nickel Alloys

These alloys are seen to be used in areas where stainless steel can’t be used due to chloride stress corrosion cracking and in parts that require high corrosion resistance. These can also be used as machined and forged valves that are utilized for seawater services.

This was everything you needed to know about copper-nickel alloys. If you are looking to invest in some amazing quality stainless steel and copper-nickel alloys, Shalco Industries is the right place for you. They have an excellent reputation and legitimate products.

Copper-nickel alloy price

Nickel Alloy products today are widely used in numerous applications across industries. But, have you ever wondered what's so special about them that they are in demand today. Using nickel alloy products has many advantages that attracts people to itself. We will be looking at it in more detail here.

It is a super alloy, meaning it has the capacity to operate at a high fraction of its melting point. It can also be called a high-performance alloy. Speaking about nickel alloy products, pipes are one of the most popular products. These pipes are readily available and are employed in many industries. Superalloy pipes can be used in aeronautics, oil and gas industries. Following, we will be outlining the benefits of opting for a nickel alloy product.

1.   Its Corrosion Resistance

This can be counted as one of the biggest advantages of using nickel alloy products. They are incredibly resistant to several types of corrosion. It may also include oxidising media which is present in many industrial environments. Nickel is naturally corrosion resistant as it is slow to oxidise at room temperatures. The properties of the products that you choose may vary depending on corrosion resistance power. For instance, Inconel alloy 625 has supreme resistance to many corrosive environments and is widely used in chemical processing.

2.   Its Heat Resistance

The temperature in the processing units at various industries is incredibly hot at all times and hence the products and materials need to withstand these extreme temperatures and conditions without warping, corroding, or losing their strength. Hence, if you choose nickel alloy products that have a high amount of chromium will be suitable for such applications. For instance, Monel alloy 400 is heat resistant to extreme temperatures. It can be widely used in heat exchanger piping and process vessels.

3.   Its Mechanical Properties

Nickel alloy products have several mechanical properties that make them suitable in industrial operations. Like, they exhibit low thermal expansion. When the expansion is exposed to high temperatures, they are likely to affect the volume, shape, and the area of the material. There are some nickel alloys like nickel-titanium, that have a good shape memory. This is a property which is pretty rare amongst most metal alloys.

Stainless steels are referred to as high-alloy steels. They have excellent corrosion resistance compared to other steels because they contain more chromium. The properties of stainless steel 446 allow it to have a very high strength-to-weight ratio. This makes it excellent for knife blades and tool handles because of its hardness and durability. This is because it can retain its strength for a long period of time and does not need to be oiled.

Stainless steel is an alloy that includes chromium, nickel, manganese, molybdenum, and carbon in addition to iron and aluminum. It is considered the hardest metal on the planet and is resistant to rust and corrosion. It has all of these characteristics, but there are different grades that vary in chromium content and other elements.

Physical Properties

Stainless steel 446 properties include its hardness, toughness, and ability to hold an edge. Its density is 7.80g/cm

Hardness: The higher the chromium levels of SS 446, the better its toughness and resistance to chipping and fracturing.

Toughness: This property accounts for how much damage a material can absorb before it breaks. Stainless steel 446 is very hard but can be scratched with a knife or file. It does not chip very easily because of the hardness of the metal so it absorbs a small amount of shock when used in a cutting direction.

Mechanical Properties

The mechanical properties of stainless steel 446 include its yield strength and ultimate tensile strength.

Yield Strength: This is the amount of stress a material can withstand without breaking when exposed to tension. The higher the chromium content, the stronger the material’s properties become. Many knife blades are made from SS 446 because it has high yield strengths that make it less likely to break when under stress.

Ultimate Tensile Strength: This is the amount of stress that can be applied to a material before it breaks or begins to deform permanently. Stainless steel 446 is strong enough to cut through many materials but the damage may occur if too much pressure is applied while cutting.

Thermal properties

One of the most important properties of stainless steel 446 is its ability to resist high temperatures without changing properties. This means that it can be used in environments that are very hot or cold. Its melting point is lower than other types of steel which means that it can be formed into shapes at lower temperatures, but it still retains its properties when the temperature changes.

There are many parts that are involved in the successful operation at some manufacturing plants and industries. One of the most important elements out of all of them is the fluid handling system in the premises. All the piping that is running along the wall, in the ceiling, and also underground, it is necessary for them to complete certain tasks. Today, we will be looking at how stainless steel pipes are the best medium to transport fluids across.

Factors You Need to Take into Consideration:

The pipes and fluid handling types of equipment need to be changed eventually just like any other system. On the other hand, if you are building a new facility altogether, choose the best piping material as you will be starting from scratch. Here, comes the decision of the type of material you need for the transportation of liquid and other fluids. This decision depends on your industry as well. Also, you need to know that this decision is not to be made lightly. Choosing the wrong pipe material has the ability to jeopardize the quality of the product. It can put in danger the safety of you and your employees as well.

Why is Stainless Steel the Best?

Stainless steel is called “stainless” for a particular reason. It does not rust or corrode easily as compared to other materials. As it contains several various alloys like chromium and molybdenum, it naturally resists corrosion. The alloys help to form a protective oxide layer on the surface. This layer is generally tough and durable. This is what guarantees you a longer and stronger span of your pipes used for the transportation of fluids. These have high tensile strength, super easy formability, and very low maintenance. To top the list, they are environment-friendly.

You can also make use of seamless pipes and seamless tubes for the same. Seamless means the absence of seam welds, which makes the pipes stronger and durable. These are known to be used widely in different applications in the oil and gas industries. The transmission and distribution of fluids can also be done without having anything to worry about.

There are many types of stainless steels. By now, we are sure that you are familiar with stainless steel 304 and its great benefits. It has not only one but many uses. And, looking at its history, we can sure tell that it has a huge role to play in the food industry. We have been coming across stainless steel cutlery since the 1910s. Skins were introduced in the 1930s, cooktops, and backsplashes in the 1940s and 1950s. Stainless steel in the kitchen really became a household name back then and as well as today. Here, we will be learning about how stainless steel plays a crucial role in the kitchen industry very effortlessly. Let us take a look into it, shall we?

Stainless steel in the food industry:

Stainless steel has proven itself and is continuing to prove to be a kitchen-safe material. As it has the power of not corroding, rusting, or harmful pathogens. The stainless steel 20th-century discovery is still making waves in the food and drink industry.

If we look forward to today, we will notice that it has not only been used in kitchens but also in commercial food applications. As much of our food is processed and sanitized well before it reaches the supermarket or our kitchen. Hence, the process needs to take place under safe and hygienic conditions only.

It has been stated that today more than 30% of the stainless steel produced is being used in the food and beverage industry. Some of those applications are mentioned below:

Hot water lines

Bulk storage

Pots and pans

Surfaces

Cutlery

Cake stands

Display stands

Hot dog rollers

Vending machines

Dispensers

What makes stainless steel food grade?

It is most likely for people to get a little confused here. Make sure you understand that not every stainless steel is applicable in food grade. Only food-grade stainless steel is ideal and sanitary. If you compare SS 304 vs SS 441, you won’t find much of a difference. They are similar. Here, we are looking at the quality, durability, and temperature resistance of stainless steel 304 which is great and suits all the requirements for the kitchen industry. It isn’t prone to oxidation or corrosion. This happens because of its high nickel content. If you compare 304 vs 430 stainless steel, you will find that 430 is used in chemical applications. It is very easy to get your hands on SS304 these days.

Stainless steel tubing is considered one of the most versatile alloy metals that are being used in manufacturing and the fabrication process. There are two main common types of tubing which are welded and seamless. The use of both types depends on the type of application and requirements of the products. While making a choice between both of them, you need to keep in mind that the tubing needs to be compliant with the project specifications. It should also meet the conditions for which the tubing is being used.

Tubing Vs. Piping:

We use these words interchangeably but you need to know that there are important distinctions between the two. Also, because they are hollow-shaped. The tubes are generally measured by outside diameter and wall thickness as well. On the other hand, a pipe is measured by its inside diameter.

Seamless tubing manufacturing:

If you want to know which tubing is the best for a certain type of application, knowing the distinction helps a lot. The manufacturing of welded and sealed tubes is evident in their names as well. Seamless tubes do not have welded seams. A tube is manufactured through an extrusion process. Here, the tube is drawn and extruded into a hollow form. Further, the tubing is shaped through pilgering, cold rolling process, and cold drawing as well.

Applications:

Oil control lines

Chemical injections

Sea safety valves

Gas transfer

Benefits:

Is very strong

Has high corrosion resistance

Has high-pressure resistance

Welded tubing manufacturing:

The production of a welded stainless steel tube is done through roll forming some strips or sheets of stainless steel into a tube shape. Welded tubes can be accomplished by hot forming as well as cold forming. Out of which, the cold forming process is comparatively smoother and finishes tighter. But, both processes create a strong and durable steel tube that will resist corrosion.

Applications:

Architectural applications

Automotive industry

Food industry

Marine industry

Pharmaceutical industry

Benefits:

Is very cost-effective

Is available in long lengths

Has fast lead times

If we talk about the costs of welded and seamless tubing, it is also dependent on durability and strength. It is worldwide accepted that seamless tubing is highly preferred to use on heavy wall tube applications because it performs high-pressure in extreme environments no matter what.

Stainless steel is formed just like any other steel with the composition of iron and carbon. However, what makes the steel stainless is the addition of chromium in its composition. Although stainless steel gets corroded or stained relatively lesser than carbon steel, they are not completely stainless. The corrosion resistant property of different stainless steel grades varies accordingly on the basis of chromium composition in the stainless steel.

Two of the most common stainless steel grades are SS 304 and SS 316. The main distinguishing factor among these grades is their chemical composition. SS grade 304 has 18% chromium and 8% nickel. And SS grade 316 comprises 16% chromium, 10% nickel, and 2% molybdenum in its composition. Due to the presence of molybdenum, SS 316 possesses enhanced corrosion resistant property and is suitable for usage in saline and chloride exposed environments.

Stainless Steel 304

SS 304 is commonly used across industries worldwide. It possesses an excellent corrosion resistance and is a great value for money. The most popular form of SS 304 is the one that contains 18% chromium and 8% nickel. However, there are other combinations as well wherein it contains about 16 to 24% chromium and up to 35% nickel along with minimal amounts of manganese and carbon.

Stainless steel 304 can resist corrosion from oxidizing agents. This grade can be easily sanitized, hence it is ideal to use in kitchen equipment, décor, buildings, and food applications. Although SS 304 possesses great corrosion resistance it cannot resist corrosion caused from chloride solutions.

Applications of 304 Stainless Steel

• Finishing hardware and fasteners

• Residential sinks

• Residential appliances

• Pots and pans

• Indoor architectural hardware

• Storage tanks

• Electrical enclosures

• Wheel covers

Stainless Steel 316

316 grade of stainless steel is the second common stainless steel used for various applications. This grade has the same mechanical and physical properties as that of SS 304. However, the prime difference is the presence of molybdenum in the chemical makeup of this steel. Molybdenum increases the corrosion-resistant property of the steel and makes it resistant to saline environments. It also gives the steel resistance to chlorides and processing chemicals. It is also used to produce medical surgical instruments.

Applications of 316 Stainless Steel

• Industrial and chemical transportation

• Pressure vessels

• Medical non-surgical equipment

• Commercial kitchens

• Marine equipment

• Food production

• Pharmaceutical equipment

• Stainless steel basket

Out of the many stainless steel sheets, we will be talking about SS 310. This grade is considered as a medium carbon austenitic stainless steel type. Especially for high-pressure temperatures like furnace parts, preheat, and heat treatment pieces of equipment. It can be used up to the temperature of 1150°C in time of continuous service and 1035°C in an intermittent type of service. It is one of the austenitic stainless steel that can be used in high-temperature corrosion as well. It is also resistant to sulfidation because of its chromium and nickel content. One can also use this in carburizing atmospheres. 

Also, grade SS310s is a low-carbon version of stainless steel 310. 310 stainless steel is widely used in typical applications which we will be learning about in detail further. Let’s get started, shall we?

Applications of SS 310:

There are a bunch of places where stainless steel 310 is seen to be used. We have listed a few which are:

1. Fluidized bed combustors

2. Radiant tubes

3. Kilns

4. Is used in a few tube hangers that are used for petroleum refining and steam boilers as well

5. Lead pots

6. Thermowells 

7. Annealing covers

8. Food processing equipment 

9. Combustion and burners chambers

10. Cryogenic structures 

11. Anchor bolts 

12. Internal components of a coal gasifier

These were some places where stainless steel 310 is used. By this, you can pretty much tell how widely used this grade is. Now that we already know the applications, let us take a look at their chemical composition. Chemical composition is something that tells us the exact distribution of several, individual substances that make a mixture. 

SS 310 stainless steel chemical composition:

There are a lot of substances that are used in grade 310. 0.25% of carbon, 2.00 max of manganese, silicon of 1.50 max. There are also other elements like phosphorus, sulphur, chromium, and nickel. These are the key substances that make the chemical composition of SS 310. It is often used in streams that contain chlorides or halides. It has improved corrosion resistance that not many alloys inherit. 

We are sure that you must be aware of what stainless steels are and some of their types as well. If not, then, the most commonly found stainless steels are austenitic stainless steel. These are known to be very high in nickel content. Also, you will find a higher amount of chromium, nitrogen, and molybdenum in them. But, stainless steels are not limited to austenitic types. One of the many is stainless steel grade 317L. Here, we will be focusing on the applications of the grade and then dive into its manufacturing and more. Stay with us till the end to know more about the SS317L.

What is stainless steel grade 317L?

To understand this in simple words, it is a version of stainless steel that has low carbon. But, on the other hand, it has the same high strength and is corrosion resistant as SS317L steel. It is known to produce stronger welds due to its low carbon content. 

Applications of stainless steel 317L:

Can be used in fuel-gas desulfurization systems

In chemical processes

Petrochemical and chemical machinery 

Pulp and paper manufacturing process 

Applicable in condensers in fossil and power generation 

In nuclear power generation stations 

In food processing 

In pharmaceutical equipments 

Various medical devices 

In portable water and marine applications 

Architectural applications that take place near the seashores in urban areas.

This says that stainless steel 317L is widely used. We will be taking a look into what the general properties of this stainless steel are. 

Additional properties:

We already know that it is a low carbonic austenitic steel with some increased additions of nickel and chromium. Because of the low carbon content, it provides a sensitization to the resistance. Especially when welded and higher creep, the stress ruptures. Also, it is non-magnetic in nature but may become slightly magnetic after the welding process. The machinability of this stainless steel represents low speeds and constant feeds. This minimizes the alloys to work hard. On the other hand, it is much tougher than 304 stainless steel. It has a long stringy chip and the use of chip breakers is highly recommended.

Have you ever wondered how many types and kinds of stainless steel are there? Well, to say the least, there are many that we yet don’t know about. One of them which we are going to focus on today is type 304 stainless steel. It is a type of stainless steel that is the austenitic grade which can also be deep drawn. This is one feature that makes this steel type a dominant one and is widely used in applications like sinks and saucepans. It is very vital to have the best quality stainless steel as they are corrosion resistant, easy to clean, and are low maintenance. It also won’t deform or even break under any circumstances, unlike any other stainless steel. 

There are two more versions of this stainless steel type and they are 304L and 304H stainless steel.

304L stainless steel:

This stainless steel is a low-carbon version. As it has low weldability, it is used more in heavy gauge components. There are some products of plates and pipes which can be used and are dual certified and hence meets the criteria of both 304L and 304H stainless steel types. 

304H stainless steel:

It is a stainless steel type that has a high carbon content and can be used at high temperatures as well. 

Properties of 304 stainless steel: 

1. It is clearly corrosion resistant in a wide range of environments. It won’t rust when in contact with different corrosive media. Be careful about the stress corrosion cracking as it can appear over 60 degrees celsius temperature and above.

2. It also has good resistance to oxidation.

3. The fabrication is done using only the dedicated stainless steel materials. 

4. Heat treatment won’t harden 304 stainless steel. 

5. 304 stainless steel also has good machinability that can be enhanced if the following is done:

Edges must be sharp at all times. 

Cuts must be light but hard enough to do the hardening work. 

Applications of 304 stainless steel:

Splashbacks and sinks

Cutlery and flatware 

Sanitaryware 

Saucepans 

Tubing

Dairy 

Brewery 

Pharmaceutical production

Nuts, bolts, and screws.
