51CrV4 ISO 683-14-2004 Oil hardened steel wire

The hardened steel wire is obtained by heating the steel wire to a certain temperature and quickly dipping into the cooling oil for quenching treatment. This process changes the structure of the steel wire, thereby increasing its hardness, strength and wear resistance.
