15CrMo steel is a heat-resistant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of steel is obvious and the weldability is poor.
40Cr hot rolled steel round bars
GB 40CR alloy Steel is a high quality Quenched and Tempered Alloy Structural steel, It belong to the high quality low carbon,Low alloy chromium, molybdenum, nickel case hardening steel. Oil Quenched & Tempered Hardness is 28-34 HRc. GB 40CR steel Annealing delivery hardenss less than 250HB.40CR With a lower carbon content range, So GB 40CR alloy steel have good weldability.
