One, 15CrMo material introduction:
15CrMo alloy steel, heat-resistant steel, pearlite, with high heat resistance at high temperature (b = 440MPa) and antioxidant activity, and has certain ability of anti hydrogen corrosion. Because of the high content of Cr, C and other alloying elements in steel, the hardening tendency of steel is more obvious, and the difference of.
Two, 15CrMo chemical composition:
C:0.12~0.18 Mn:0.40~0.70 Si:0.17~0.37 Cr:0.80~1.10 Mo:0.40~0.55 Ni: = 0.30, S: = 0.035, P: = 0.035
Three, mechanical properties of 15CrMo:
440~640: the tensile strength yield point elongation of 21: 235
