The metal structure of 1Cr5Mo is martensite, which has good oxidation resistance at about 650 degrees Celsius, good thermal strength below 600 degrees Celsius, and good shock absorption and thermal conductivity. It is widely used in steam turbines. However, this type of steel has a greater tendency to harden, and its welding performance is poor. 5-70MM thick, can be rolled futures. Main application: high temperature hydrogen and hydrogen sulfide corrosion, organic acid corrosion. Reheater tube with wall temperature of 630℃-650℃.
