Cold Stamping Steel
for Case hardening
Steels designed to harden the surface layer
This group includes construction steels, with carbon <0.30%, intended for the surface hardening treatment of cementation. This process of carbon enrichment of the surface of the piece and the subsequent hardening, give a high surface hardness with an excellent resistance to wear, while the low carbon content of the core allows high core toughness values.
Thanks to the high surface hardness obtainable with the carburizing treatment, these steels are usually used for the construction of mechanical parts subject to wear such as: gears of any type, axles, cones, pins, bushings, nuts, and everything needed for the motion transmission.
