What is 42CrMo4 steel number

42CrMo4 steel is EN standard alloy steel. It belongs to mold steel in terms of material classification. 42CrMo4 steel has good mechanical properties and machinability, and has wide application. 42CrMo4 steel is usually in forms of 42CrMo4 steel plates and 42CrMo4 round bars. Among them, 42CrMo4 steel plates are mainly used for mold processing and 42CrMo4 round bars are used for mechanical direct processing parts, which have been recognized by the industry. What is 42CrMo4 steel number?

42CrMo4 steel number is 1.7225. 42CrMo steel is a kind of ultra-high strength steel. The ultra-high strength steel must have high tensile strength, enough toughness, high specific strength (ratio of strength to density) and high yield ratio (σs / σb), so as to reduce the weight of components. 42CrMo4 steel also has good weldability and formability.
