GB/T 3077 15CrMo alloy steel
GB/T 3077 15CrMo alloy steel
The 15CrMo steel pearlite heat-resistant steel, high hot strength (δb ≥ 440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. As the steel contains a higher content of Cr, C, and other alloying elements, the steel hardened tendency obvious, poor welding.
