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.

VASCO M-33 is a high-molybdenum high-speed steel containing 8% cobalt which contributes materially to the superior red hardness of the steel. It is recommended highly for tools that require the optimum combination of high-temperature hardness, resistance to wear and cutting edge strength and retention. Typical applications for VASCO M-33 include broaches, end mills, lathe tools and drills. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: TS-413. Producer or source: Teledyne Vasco.

AISI Type M33 is a heavy-duty high-speed steel; it contains 8.00% cobalt to improved red hardness. It is recommended for cutting-tool applications in which wear resistance and high temperature hardness are important characteristics. It should not be used where excessive shock and/or chatter are encountered. AISI Type M33 is well suited to uses 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 forming, heat treating, and machining.
