What is SS 304?

SS 304 is an austenitic stainless steel composed of:

18% Chromium (Cr) – Provides corrosion resistance.

8% Nickel (Ni) – Enhances strength and durability.

Low Carbon Content – Improves weldability.

Advantages of SS 304:

✅ Good corrosion resistance in mild environments. ✅ Cost-effective and widely available. ✅ Ideal for general-purpose applications like food processing, kitchenware, and structural elements.

What is SS 316?

SS 316 is an upgraded version of SS 304 with the addition of molybdenum (Mo). It contains:

16-18% Chromium (Cr) – Provides oxidation and rust resistance.

10-14% Nickel (Ni) – Enhances strength and toughness.

2-3% Molybdenum (Mo) – Increases resistance to pitting and crevice corrosion.

Advantages of SS 316:

✅ Superior corrosion resistance in marine and acidic environments. ✅ High temperature and pressure tolerance. ✅ Commonly used in chemical plants, medical equipment, and marine structures.

304 Stainless Steel Properties & Benefits

304 stainless steel is the most commonly used austenitic stainless steel due to its corrosion resistance, strength, and high durability. It contains:

18% Chromium (Cr): Provides oxidation and rust resistance.

8% Nickel (Ni): Enhances strength, ductility, and durability.

Low Carbon Content: Improves weldability and prevents carbide precipitation.

Why Choose 304 Stainless Steel Flanges?

✅ Corrosion Resistance: Performs well in harsh environments, chemical industries, and marine conditions. ✅ Heat Resistance: Withstands temperatures up to 870°C (1598°F). ✅ High Strength: Suitable for industrial and heavy-duty applications. ✅ Versatile Applications: Used in pipelines, food processing, medical equipment, and manufacturing.
