1Cr5Mo steel is a martensitic metal structure.1Cr5Mo has good oxidation resistance around 650 degree , good thermal strength below 600 degree , and good vibration damping and thermal conductivity.1Cr5Mo steel is widely used in steam turbines.15CrMo steel plate is a heat-resistant steel with pearlitic structure.15CrMo steel plate is a heat-resistant steel with pearlitic structure.
15CrMo steel plate is a kind of heat-resistant steel with pearlitic structure, with high thermal strength (δb Greater than or equal to 440MPa) and high-temperature oxidation resistance, and a certain degree of hydrogen corrosion resistance. Due to the high content of Cr, C and other alloying elements in the steel, the steel hardening tendency is obvious, and the weldability is poor.
