What are the properties of 15CrMo steel?

15CrMo grade under GB/T 3077-2015 is an alloy structural steel material. This standard specifies the 15CrMo steel hot rolled steel bars and forged steel bars with diameter less than 250mm.

Properties of 15CrMo steel

At high temperature, 15CrMo alloy has high thermal strength (δb≥440MPa) and oxidation resistance, and has a certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of 15CrMo steel is obvious, and the weldability is poor. 15crmo alloy steel plate weight calculation formula: length × width × thickness × 0.00785 = kg / m. 15CrMo alloy steel is mainly used in petroleum, petrochemical, high-pressure boilers, etc. Seamless pipes for special purposes include seamless pipes for boilers, seamless steel pipes for geology and seamless pipes for petroleum.
