309/309S Stainless Steel
Our inventory now includes Alloy 309/309S (UNS S30900/S30908) in sheet, sheet coil, plate, round bar, processed flat bar and tubular products.
Alloys 309 and 309S are austenitic chromium-nickel stainless steels that are often used for higher temperature applications. Due to their high chromium and nickel content, Alloys 309 and 309S are highly corrosion resistant, have outstanding resistance to oxidation, and excellent heat resistance while providing good strength at room and elevated temperatures. The only significant difference between 309 and 309S is the carbon content. Alloy 309S has a much less carbon composition which minimizes carbide precipitation and improves weldability.

310/310S Stainless Steel
Our inventory now includes 310/ 310S Plate and Processed Flat Bar (Alloy 310 UNS S31000 / Alloy 310S UNS S31008), ideally suited for high-temperature applications such as heat treatment and chemical processing equipment.
Alloy 310 is an austenitic stainless steel that combines excellent high temperature properties with good ductility and weldability. It is typically used for elevated temperature applications as its high chromium and nickel content provide solid corrosion resistance, excellent resistance to oxidation, and superior strength in temperatures up to 2100°F. Due to its high chromium and nickel content, it is superior to 304 or 309 stainless in most environments.

310H Stainless Steel
Our inventory now includes 310H Plate and Processed Flat Bar (Alloy 310H UNS S31009), ideally suited for high-temperature applications such as heat treatment and chemical processing equipment.
Alloy 310H (UNS S31009) has a carbon content restricted to exclude the lower end of the 310 range. This makes 310H the grade of choice for high temperature applications. This steel has good resistance to oxidation at temperatures of up to 1040°C (1904°F) in intermittent service and 1150°C (2102°F) in continuous service. It is widely used in environments where sulfur dioxide gas is present at high temperatures; however it is recommended that this steel should not be continuously used at 425-860°C (797-1580°F) range due to carbide precipitation.

330 Stainless Steel
Our inventory now includes 330 stainless steel Plate and Processed Flat Bar (Alloy 330 UNS N08330), ideally suited for demanding, high-temperature, high-pressure applications such as chemical and petrochemical processing, thermal processing, ore processing, and power generation.
Alloy 330 is an austenitic, nickel-chromium-iron-silicon alloy that has outstanding resistance to oxidation and carburization up to 2200°F with high strength. The excellent resistance to oxidation and carburization is provided by the high nickel and chromium content of the alloy, further enhanced by its silicon content. Alloy 330’s ultra high nickel content of 34 to 37% also provides high resistance to chloride stress corrosion cracking and embrittlement from the precipitation of sigma phase in most furnace atmospheres. Alloy 330 also has a low coefficient of expansion, excellent ductility, and high strength.
