What Are CR Sheets? 

CR sheets or cold rolled sheets are steel sheets processed in cold reduction mills. The sheets are produced by rolling hot steel at room temperature once it has been cooled from the hot rolling process. Cold rolling process strengthens the sheet, enhances surface finish, and increases dimensional accuracy than hot rolled steel. 

While hot rolled steel plates are better suited for structural parts and uses that do not entail close tolerances, cold rolled steel sheets have advantages that render them imperative in precision industries. 

Advantages of Cold Rolled Sheet 

Let us discuss the particular benefits that make cold rolled sheets best suited to various uses. 

1. Better Surface Finish 

One of the most pronounced benefits of cold rolled sheets is their better surface finish. In the cold rolling process, the steel goes through polished rollers, which provide a smoother and finer surface compared to hot rolled sheets. 

This smooth surface not just appears superior but is also more appropriate for uses where appearance and coating are essential, including: 

Automotive panels 

Home appliances 

Furniture 

Office equipment 

A smooth, clean surface also improves adhesion of paint and coatings, enhancing corrosion protection and appearance. TATA CR sheets are particularly favored in sectors where finish and appearance are important. 

2. Improved Flatness 

In comparison with hot rolled steel, CR steel sheets possess significantly improved flatness and even thickness. Cold rolling presses the steel precisely with a reduction in dimensions to ensure minimal, if any, warping or distortion in the finished product. 

This degree of flatness is important in cutting, welding, or forming manufacturing operations where any deviation will cause inconsistency or defects in the finished product. Therefore, industries opt for cold rolled steel sheets for precision applications. 

Parco Engineers, a major TATA CR sheet distributor, supplies customers with uniformly flat sheets that adhere to the highest quality expectations. 

3. Uniform Mechanical Properties 

Another significant advantage of cold rolled sheets is their uniform mechanical properties throughout the sheet. Their tensile strength, hardness, and ductility are made consistent through controlled processing and quality control at every stage. 

Mechanical property uniformity is particularly critical in industries like: 

Automotive production 

Electrical appliances 

Engineering components 

By using TATA CR sheets, you are assured of uniform performance, minimizing the risk of product failure and maximizing your end product's reliability. 

4. Better Drawability 

Cold rolled sheets have improved formability and are easier to bend and shape compared to hot rolled sheets, owing to their improved drawability. They can therefore be pressed, bent, or drawn into complex shapes without cracking or losing strength, making them perfect for deep drawing applications. 

TATA Steelium Super CR Sheets are designed with superior drawability in focus. This renders them ideal for uses such as: 

Car body panels 

Electrical enclosures 

Kitchen appliances 

Metal furniture 

The CR sheet has strength even after forming, enabling intricate designs and strong constructions.

Throughout this blog post, we shall cover all that you need to know about hot rolled steel sheets — starting with the manufacturing process up to the main advantages, uses, and benefits.

What Are Hot Rolled Steel Sheets?

Hot rolled steel sheets are steel rolls that are rolled while hot — usually over 1700°F (926°C). Steel is malleable and soft at this temperature, making it easy to form. The hot rolled sheet is then rolled through sets of rollers to give it the desired thickness and size.

Unlike cold rolled sheets, which are rolled at room temperature to create a smoother and more accurate finish, hot rolled steel sheets are typically utilized in applications where precise dimensions aren’t essential. Still, they have many advantages that make them the perfect choice for structural purposes and projects that need strong, tough, steel.

TATA Astrum HR sheets, which can be found at Parco Engineers, are among the most trusted HR sheet products to be found in the market, renowned for their strength, affordability, and versatility.

How Are Hot Rolled Steel Sheets Formed?

The process of manufacturing hot rolled steel plates starts from a big billet of steel that is heated to a temperature above its recrystallization temperature. After getting heated enough, it is rolled through a number of rolling mills that thin it out but lengthen it.

Here’s a step-by-step process:

Heating: The steel slab is heated at high temperatures (above 1700°F).

Rolling: It is rolled over rollers to create sheets, plates, or coils.

Cooling: The steel sheets in the hot rolled condition are left to cool to room temperature, producing a scaled finish.

Cutting: The steel is cut to desired lengths or rolled into coils and processed further.

The finished hot rolled sheet or plate can have minor thickness and surface finish variations, which is not a problem for most of its structural uses.
