1.2738HH die steel characteristics
Excellent polishing and photoetching performance; Excellent machinability; Good wear resistance; The large mold has uniform hardness and dense organization; No quenching crack and heat treatment deformation risk, no heat treatment, shorten the mold production cycle; Good surface nitriding performance; The surface flame hardening can be carried out to improve the surface hardness and wear resistance of the mold.
