45NiCrMo16, 1.2767, 40NiCrMo16 steel - specifications and applications
Alloy cold working steel with very high hardenability, ductility, resistance to pressure, abrasion and high impact strength. The material is used for the production of shears for cutting steel sheets and sections, stamping dies, hydraulic chisels, cold forging dies, hardened knives, stamps, punches or moulds for the production of plastics. The grade is characterized by high strength, load resistance, tempering and fatigue resistance. The grades 45NiCrMo16 and 40NiCrMo16 have been enriched with additional content of nickel, and molybdenum in the chemical composition.
