Applications and advantages of SS 316

Why Udhhyog is the preferred supplier for SS 316 flanges

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.
