It has higher strength and hardenability than 20CrMnTi steel, but the impact toughness is slightly lower. Mainly used as carburized steel, after carburizing can be cooled and quenched directly, high bending strength and good wear resistance. It can be used after quenching, low-temperature tempering or tempering, and has medium machinability. It is used to manufacture heavy-duty carburized parts with large cross-sections and gears, gear shafts, worms, etc. with large force in the tractor industry.
