Carpenter Stainless No. 2 Mold Steel is a 13% chromium steel ideally suited for long-run molding jobs. It is specifically used for protection against the following corrosive conditions: (1) Rusting of cavities when machines are shut down or molds are stored, (2) Rusting of mold cavities when using corrosive plastics, and (3) Corrosion problems when molds are used in hot, humid climates. In addition to resisting the above corrosive conditions, users have found that this steel has many other cost-reducing advantages for applications where corrosion is not involved. 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, and machining. Filing Code: SS-367. Producer or source: Carpenter.
