10CrMo910 boiler tube is a pearlitic heat-resistant steel, primarily used in superheaters with wall temperatures below 590°C and in headers/steam pipelines with wall temperatures around 540°C, designed to withstand a pressure of 13.2 MPa. It enters the third stage of creep when the elongation reaches 3%-5%. This material is widely applied in various heat-exchange surface pipes across thermal power, nuclear power, and petrochemical industries.
