Product Description 42CrMo is an ultra-high strength steel, known for its high strength, high toughness, good hardenability and tempering stability. This steel is widely used in the manufacture of mechanical parts and moulds that require high strength and toughness.42CrMo steel belongs to ultra-high-strength steel, with high strength and toughness, hardenability is also good, no obvious tempering brittleness, tempering treatment has a high fatigue limit and resistance to multiple impacts, low-temperature impact toughness is good. 42CrMo steel is suitable for the manufacture of requirements of a certain degree of strength and toughness of the large and medium-sized plastic moulds.42CrMo chemical compositionCarbon C :0.38~0.45%Silicon Si :0.17~0.37%Manganese Mn :0.50~0.80%Sulphur S :permitted residual content ≤0.035Phosphorus P :permissible residual content≤0.035Chromium Cr :0.90~1.20%Nickel Ni: allowed residual content ≤ 0.30%Copper Cu: Residual content allowed ≤ 0.30%Molybdenum Mo:0.15~0.25%Mechanical Properties of 42CrMo SteelHardness : Annealed,147~241HB42CrMo mechanical properties:Tensile strength σb (MPa): ≥1080(110)Yield strength σs (MPa): ≥930(95)Elongation δ5 (%): ≥12Section shrinkage ψ (%): ≥45Impact work Akv (J): ≥63Impact toughness value αkv (J/cm2): ≥78(8)Hardness :≤217HBIn order to improve the life of the mould to achieve more than 800,000 die times, can be implemented on the pre-hardened steel quenching and low-temperature tempering of the hardening method to achieve. Quenching in 500-600 oC preheating 2-4 hours, and then in 850-880 oC insulation for a certain period of time (at least 2 hours), into the oil cooling to 50-100 oC out of the oil air-cooled, quenched hardness of up to 50-52 HRC, in order to prevent cracking should be carried out immediately 200 oC low-temperature tempering treatment, tempering, hardness can be maintained more than 48HRCOur Promise1.
