MIRROMOLD is a case-hardening mold steel designed expressly for cold-hobbed cavities. It is a vanadium-treated, cold-melt, electric-furnace mold steel developed to provide: (1) Cleanness and uniformity, (2) Maximum hobability and (3) Uniform response to heat treatment. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as deformation. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: TS-305. Producer or source: Carpenter.
