RA410 and 410S are two of the most widely used hardenable stainless steels. RA410S is the lower-carbon version, which permits it to be more readily welded. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, and joining. Filing Code: SS-961. Producer or source: Rolled Alloys.
