CrV alloy steel grades and application

Posted:2021-03-25 10:51:38

20CrV alloy steel: Used for carburized parts that require high hardness and wear resistance on the surface, high strength in the core but small cross-section, such as gears, piston pins, turbine transmission gears, small shafts, distribution shafts, ejector rods, etc.; heat resistance nuts and washers (working at 300-500℃) on steam turbines; high-pressure pipelines working in non-corrosive media, etc.

40CrV alloy steel: Used as important crankshafts, crank wheels, push rods, high-load bolts, locomotive connecting rods, propeller bearing brackets, mold beams, etc.

50CrV alloy steel: Used as important parts for large cross-sections below 400 ℃ and particularly important springs of various sizes that bear high stress, etc.
