What is SS 316? Understanding Material Properties
SS 316 is a molybdenum-containing stainless steel alloy that provides superior corrosion and heat resistance compared to SS 304. It consists of:
16-18% Chromium (Cr): Ensures oxidation and rust protection.
10-14% Nickel (Ni): Enhances toughness and durability.
2-3% Molybdenum (Mo): Improves resistance to pitting and crevice corrosion, especially in marine and acidic environments.
Key Benefits of SS 316 Stainless Steel
✅ Corrosion Resistance: Excellent protection against chloride exposure, acids, and marine conditions.
✅ High Strength & Durability: Withstands extreme pressure and high temperatures.
✅ Heat Resistance: Maintains stability up to 870°C (1598°F) in continuous operations.
✅ Chemical & Food Safe: Ideal for food processing, pharmaceuticals, and chemical industries.
