1.7147 carburized steel

1.7147 material is carburized steel (case hardening steel) with high strength and toughness and good hardenability. The quenching deformation is small, the low temperature toughness and the machinability are good, but the welding performance is low. It’s generally used after carburizing quenching or quenching and tempering.
