GB/T 3077 15CrMo alloy steel
15CrMo Steel pipe material grade is 15CrMo, is a high-quality low-alloy structural steel, which contains CR, MO more, its high temperature, corrosion-resistant performance is very good.
The 15CrMo-series Pearlite-heat-resisting steels have high thermal strength (Δb≥440mpa) and anti-oxidation at high temperature, and have certain capability of resisting hydrogen corrosion. Because of the high content of CR, C and other alloying elements in steel, the hardening tendency of steel is obvious and the weld ability is poor.
