Material:
20CrMoStandard: alloy structural steel
GB 3077 20CrMo grade steel is a kind of alloy structural steel. This 20CrMo heat-resistant steel has high heat strength (δb≥440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in the steel, the hardening tendency of the steel is obvious and the weldability is poor.
