Vasco Momarc CVM is a modification of AISI 52100 steel where the manganese has been replaced by molybdenum to provide the desirable hardenability. It is more resistant to tempering than 52100 which makes it ideal for bearing applications. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, machining, and joining. Filing Code: SA-192. Producer or source: Vanadium Alloys Steel Company.
