VASCO X-2 CVM is a steel designed especially for gears and shafts where a high surface hardness (carburized) and superior hot hardness are desired. It is a vacuum-melted steel and provides an excellent combination of high strength, good toughness and high fatigue strength. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness and fatigue. It also includes information on high temperature performance as well as forming, heat treating, machining, and joining. Filing Code: TS-261. Producer or source: Teledyne Vasco.
