DIN17175 12Cr1MoV alloy steel pipe

Compared with 12CrMoV steel, 12Cr1MoV has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV is very close to the permanent strength value, and it has high plasticity in the case of long-lasting tension; the steel has good processability and weldability, but it needs to be preheated to 300°C before welding, and the stress treatment after welding is required.
