Product Introduction

NAK80, P21, 40 HRC pre-hardened, high performance, high precision, mold steel. Equivalent grades: DIADO NAK80,

HITACHI HPM50,EVERGCREEN GK2003,ASTM P21 (Optimized steel),HJ HAbI-70,GB 10Ni3MnCuAl

Features:
• Machines up to 20% faster than 30 HRC P20
• Hardening up to 37-43HRC can be inscribed and used in the original mould of processing,heat treatment is not needed.
• Uniform microstructure & hardness (40 HRC between surface & interior)

• After Ni-Al-Cu age-hardening steel discharge, the grinding processing is easy.

• Good weld ability, HAZ gets softer not harder (re-age harden to bring back to 40 HRC), can be used to maintain high-precision,the hardness of the surface and central is uniform.

• Never need stress relieving, even after heavy machining
• EDM layer is easy to remove

• Special melting Excellent precision of grinding,satisfactory brightness,good process ability of corrosion took,detailed surface discharge, fine flat pretty machined surface.

• Corrosion Steel.
