VASCO M-50 is a hardenable (martensitic), low-alloy high-speed steel developed primarily for high-strength, high-load components (such as bearings and gears) designed for elevated-temperature service. It may be used at temperatures up to 600 F; this is in contrast to AISI 52100 steel which may be used up to only 350 F. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, machining, joining, and surface treatment. Filing Code: TS-278. Producer or source: Teledyne Vasco.
