Abstract

MOLITE 42 is a molybdenum-type super high-speed steel. It has a well-balanced composition designed to give superior performance when used for difficult machining operations. It can be heat treated to a hardness level of Rockwell C 68-70 giving excellent red hardness while maintaining moderate toughness. MOLITE is especially recommended for tools used in the machining of high-strength steels, prehardened steels and exotic ferrous and nonferrous alloys such as are used in aircraft and missile work. It is also recommended for ordinary machining jobs requiring long production runs. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-487. Producer or source: Columbia Tool Steel Company.
