42CrMo ALLOY STEEL TUBE

42CrMo chemical composition and mechanical properties:   chemical composition:   Carbon C  0.38～0.45% Silicon Si  0.17～0.37% Manganese Mn  0.50～0.80% Sulfur S  Allow residual content ≤0.035% Phosphorus P  allowable residual content ≤0.035% Chromium Cr  0.90～1.20% Nickel Ni  allowable residual content ≤0.30% Copper Cu  allowable residual content ≤0.30% Mo  0.15～0.25%     Mechanical properties: Hardness: Annealing, 255～207HB, indentation diameter 3.8～4.2mm; Quenching, ≥60HRC cr12mov The hardenability, hardness, strength and toughness after quenching and tempering are higher than CR12, and the work with a diameter of 300-400mm or less can be completed Hardenable, small quenching deformation, but poor high temperature plasticity. cr12mov plates are mostly used to manufacture composite molds and tools with large cross-sections, complex shapes and heavy workloads.
