LESCALLOY M50 VIM-VAR is produced exclusively as a double-vacuum-melted product using the vacuum induction melting plus VAC-ARC remelting process. This provides the optimum in control and reproducibility of chemistry, microcleanliness and superior fatigue resistance. This grade has high hardness and high compressive strength at temperatures up to about 800 F. It is used widely for highly stressed parts such as aircraft bearings and gears for elevated-temperature service. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fatigue. It also includes information on low and high temperature performance as well as forming, heat treating, machining, and surface treatment. Filing Code: TS-415. Producer or source: Latrobe Steel Company.
