12Cr1MoV alloy steel is a kind of low carbon steel, containing high Cr, Mo and other alloying elements, with good high temperature strength and creep strength, able to withstand high temperature and high pressure working environment. In addition, 12Cr1MoV alloy steel has good corrosion and oxidation resistance, and can work in acidic or alkaline environment for a long time.
The preparation process of 12Cr1MoV alloy steel mainly includes smelting, casting, rolling and heat treatment. First, the raw materials are smelted to remove impurity elements and add appropriate amount of alloying elements; second, the smelted steel is cast to form ingots; again, the ingots are rolled and processed into the required shape and size; finally, heat treatment is carried out to adjust the mechanical properties and corrosion resistance of the material.
12Cr1MoV alloy steel is widely used in national defense, nuclear power, petrochemical, electric power, boiler manufacturing and other fields. In nuclear power plants, 12Cr1MoV steel plate is used to manufacture pressurized water reactor pressure vessels, which have very good radiation resistance and can operate stably for a long time in a high radiation environment. In addition, in the boiler manufacturing industry, 12Cr1MoV steel plate is widely used in the manufacture of various parts of high-temperature and high-pressure boilers, such as pipes, joints, flanges and support structures.
