42CrMo steel plate belongs to national standard high strength alloy structural steel, executive standard: GB / T 3077-1999.
42CrMo steel plate has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering treatment, and good low temperature impact toughness. 42CrMo steel plate is suitable for manufacturing large and medium-sized plastic moulds with certain strength and toughness.
Chemical composition of 42CrMo steel plate
C: 0.38-0.45%, Si: 0.17-0.37%, Mn: 0.50-0.80%, S≤0.035%, P≤0.035%, Cr: 0.90-1.20%, N≤0.30%, Cu≤0.30%, Mo: 0.15～0.25%.
42CrMo steel plate is a kind of plastic mould steel in mould steel according to material classification. It has good mechanical properties and machinability, and is widely used. 42CrMo steel plate mainly has two types of materials: plate and round bar. 42CrMo steel plate is used for mold processing and production, and round bar is used for mechanical direct processing of parts, which has been recognized by the industry.
