The 15CrMo steel plate is a pearlitic heat-resistant steel with high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and possesses certain resistance to hydrogen corrosion. Due to the higher content of Cr, C, and other alloying elements in the steel, the steel has a pronounced tendency to quench harden and poor weldability.
