12CrNi2 alloy structural seamless steel pipe is a kind of advanced carburized steel with good comprehensive mechanical properties.
The chemical composition of 12CrNi2 structural seamless steel pipe includes carbon, silicon, manganese, sulfur, phosphorus, chromium, nickel and copper. Its mechanical properties include tensile strength, yield strength, elongation, area shrinkage, impact energy and impact toughness value. wait. The heat treatment specifications for this steel pipe are quenching and tempering, where the quenching temperature is 860°C for the first time and 780°C for the second time, water-cooled or oil-cooled; the tempering temperature is 200°C, water-cooled or air-cooled.
12CrNi2 alloy structural seamless steel pipe is mainly used to manufacture parts requiring higher strength and toughness, such as gears, shafts, piston pins, etc.
