Stainless Steel Seamless Tube

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. Specifications: UNS S30900/S30908

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.
