BOFORS BP20-2 is a vacuum-degassed (BOVAC) alloy tool steel recommended for plastic molds, brake dies, die-casting dies for tin, lead and zinc alloys, and for constructional parts. It is supplied prehardened to 270-300 Brinell and needs no further heat treatment before use; however, it may be heat treated for a number of applications that require higher hardness and strength. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, machining, joining, and surface treatment. Filing Code: TS-263. Producer or source: Bofors Steels Inc..
