Alloys 309S is austenitic chromium-nickel stainless steel that is often used for higher temperature applications. Due to their high chromium and nickel content, Alloys 309S is highly corrosion resistant, has 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.
Alloy 309H Coils has some other features to offer such as precisely designed, rust proof, optimum finish, high strength, low maintenance, enhanced service life, and more.
