439 Stainless Steel Coil and Sheet

439 stainless steel is an 18% chromium, titanium-stabilized, low-carbon austenitic-ferritic stainless steel. Its corrosion resistance is similar to that of 304/304L stainless steel, and it is designed to resist a variety of oxidizing environments from fresh water to boiling acids. This grade has good weldability due to the stabilizing effect of titanium, and it also exhibits excellent resistance to stress corrosion cracking. 439 does not require post-weld annealing to restore ductility or provide resistance to intergranular corrosion. 439 also has excellent formability and is widely used in the automotive industry, with typical applications including tubular manifolds and exhaust system components. It can be slightly hardened to increase tensile strength.
