Main characteristics of 12Cr1MoV Steel: compared with 12CrMoV steel, 12Cr1MoV steel has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is very close to the endurance strength value, and it has high plasticity under the condition of endurance tension; the processability and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress removal treatment after welding. 12Cr1MoV steel is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical utility boiler.

Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, S355MC pickling steel coil company.
