What is the application of CrNi alloy steel materials

20CrNi alloy steel: Used as gears, shafts with higher toughness, etc.

40CrNi steel: Used as gears, shafts of heavy machinery, steam turbine blades, rotors and shafts, couplings and other structural parts that require high toughness and high strength.

45CrNi 50CrNi steel material: Used as high-load gears, small shafts, pins, important bolts, turbine wheels, rotors.

12CrNi2 steel: Used as carburizing gear, small shaft, high toughness piston rod.

12CrNi3 alloy steel: Used as high-load carburized gears, small shafts and pins, etc.

20CrNi3 alloy steel: Used as high-load gears, shafts, etc.

30CrNi3 steel: Used as high-load gears, multi-slot shafts, keys, etc.

37CrNi3 steel: Used as important hardened and tempered parts of large section, such as shaft, direction shaft, front shaft, transmission shaft, crankshaft, joystick, die, etc.

12CrNi4 steel material: Large-scale carburized parts with complex shapes that work under vibration and dynamic loads, such as crankshafts, crankshafts, gears, etc.

20Cr2Ni4 steel material: Used as carburizing and quenched and tempered structural parts with higher strength requirements.

20CrNiMo 40CrNiMo steel: It is used as the more important quenched and tempered structural parts that require high strength, high toughness, large cross-section, such as the transmission eccentric shaft of the horizontal forging machine, the crankshaft of the forging press, etc.

45CrNiMoV steel: High-strength quenched and tempered steel is used for parts that require high strength and large size to withstand high loads.

18Cr2Ni4W alloy steel: Same use as 12Cr2Ni4, manufacturing advanced carburized structural parts.

25Cr2Ni4W alloy steel: The use is the same as 12Cr2Ni4.
