-Adopting Vacuum Degassing (VD) production technology to refine, gurantee lower content of impurities and gas
-Supplied in pre-hardened condition, directly machining and without heattreatment
-Excellent mirro polishability
-Purify quality, outstanding texturing and EDM machinability
-Excellent Nitriding properties, surface nitriding could extend the service life of molds after hardening
