CARPENTER STAINLESS TYPE 405 is a 12% chromium stainless steel that does not harden appreciably. It was designed to allow its use in the as-welded condition. It is particularly desirable for welded applications which require finish machining. It has moderate tensile strength (70,000 psi) in the fully annealed condition and resists corrosion in mild environments. It is used for parts and structures that cannot be annealed after welding. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-395. Producer or source: Carpenter.
