AL Tech Super LMW-Extra is high-molybdenum high-speed steel containing 8.25% cobalt to improved red hardness. It is most useful for cutting-tool applications in which wear resistance and high-temperature hardness are important properties. This grade should not be use where excessive shock or chatter are encountered. Super LMW-Extra is well suited to applications such as machining hard and heat-treated materials and machining both ferrous and nonferrous aircraft alloys. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on high temperature performance as well as heat treating and machining. Filing Code: TS-388. Producer or source: AL Tech Specialty Steel Corporation.
