We are offering premium-quality products suitable for high-temperature and corrosion-resistant applications. Grade 309 is an austenitic chromium-nickel stainless steel specifically designed to provide excellent oxidation resistance and superior heat strength. Our 309S SS Sheets are widely used in industries that demand durability, strength, and resistance to extreme temperatures.
The primary difference between 309 and 309S is the carbon content:
309 Stainless Steel
- Higher carbon content
- Better high-temperature strength
309S Stainless Steel (UNS S30908)
- Low carbon version of 309
- Reduced carbide precipitation
- Improved weldability
- Ideal for fabrication applications
The lower carbon content in 309S Stainless Steel Sheets minimizes intergranular corrosion after welding, making it suitable for welded structures.
ASTM A240 Type 309S Stainless Steel Sheets:
- Excellent resistance to oxidation
- High resistance to scaling
- Good mechanical strength at elevated temperatures
- Easy fabrication and forming
309S is commonly used in furnace parts, heat exchangers, kilns, boiler components, and heat treatment baskets.
