P20+S/P21 Nak80 1.2312 Forged Annealed Turned Surface Plastic Mould Steel

Product Description

P20+S/P21 NAK80 1.2312 Forged Annealed Turned Surface Plastic Mould Steel

1: NAK80 steel introduction
    NAK80 steel is a precipitation or age-hardened mold steel with a uniform through hardness of approximately 40 HRC. It is super clean, Vacuum-Arc Remelted steel with uniform grain structure, uniform hardness, and excellent dimensional stability. NAK80 tool steel is the improved steel grade of NAK55, on mirror surface, EDM surface and toughness.
