441 Stainless Steel Sheet / 1.4509

441 Stainless Steel Sheet / 1.4509

1.4509 is a low carbon, dual stabilised (titanium and niobium) ferritic stainless steel containing 18% chromium. It has good corrosion resistance in moderately corrosive environments and good oxidization and creep resistance at elevated temperatures. In the annealed condition 1.4509 is ductile, does not work harden and can be formed using a variety of roll forming, bending or mild pressing/ stamping operations. 1.4509 is resistant to stress corrosion cracking but has limited weldablity. 1.4509 should not be used in the as-welded condition for dynamic or impact loaded structures.
