15CrMo ASTM A335 P12 Hot Rolled Boiler Steel Alloy Steel Tube
Specification
15CrMo steel is a pearlite structure heat resistant steel with high thermal strength (δ B ≥440MPa) and oxidation resistance at high temperature, and has a certain hydrogen corrosion resistance. Due to the high content of Cr, C and other alloying elements in the steel, the hardening tendency of the steel is obvious and the weldability is poor.
