12CrMoV Alloy Structure Steel

12CrMoV alloy structure steel is an alloy steel used primarily in the field of engineering construction. This steel has the characteristics of low cost, wide range of applications, good potential of steady development, and easy to process. This steel is mainly used in the fields of Power engineering, Chemical industry, Metallurgy, etc.

The composition of 12CrMoV alloy steel includes 12% of Chromium, 0.20-0.30% of manganese, 0.2% of silicon, 0.2% of molybdenum, 0.20-0.30% of vanadium, 0.1-0.15% of tungsten, and a small amount of carbon and other elements. The chromium-molybdenum-vanadium content of 12CrMoV alloy steel has been increased, which can effectively improve the low temperature embrittlement of the steel and enhance the creep strength of 12CrMoV alloy steel.

12CrMoV alloy steel has excellent heat resistance, good corrosion resistance, strength, wear resistance, fatigue strength, creep strength and other mechanical properties. After heat treatment, 12CrMoV alloy steel can reach an even higher level of hardness, strength, wear resistance and corrosion resistance.

12CrMoV alloy steel can be used in the manufacture of power boilers, nuclear reactors, gas turbines, high and low temperature pressure vessels, pressure pipes, petrochemical equipments, and in the manufacture of turbines, high temperature strength bolts, nuts and other fasteners. It is also used to make heavy-duty forgings, heat-resistant lorries,and forging parts.

In addition to its good mechanical properties, 12CrMoV alloy steel also has good weldability. It is easy to weld with conventional welding processes such as gas welding, arc welding and submerged arc welding. However, when welding with arc welding, small welding current, low welding speed and multiple welding pass should be applied. During the welding process, appropriate welding materials and appropriate welding parameters should be selected, such as welding layer thickness, welding wire diameter, welding current, welding voltage, etc., to ensure good welding quality.

In conclusion, 12CrMoV alloy structure steel is a low-cost, wide range of applications, good development potential and easy-to-process steel. Its heat resistance, corrosion resistance, strength, wear resistance, fatigue strength, creep strength and other mechanical properties are excellent, and its good weldability makes it an ideal choice for many fields.
