Product Description
Plate Steel 1.2312 NAK80 P20+S P21 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.

7: NAK80 Steel Application
NAK80 tool steels are used for transparent products and others for which mirror finished surface are particularly important; Products for which electrical discharge machined surfaces are very important; Typical for clear lens molds, extremely critical diamond finish applications, and molds requiring special EDM finish.
8: NAK80 Steel Heat Treatment
Soft Annealing
Heat NAK80 steel to 640-660oC, cool slowly. This will produce a maximum Brinell hardness of 330.
Hardening
Harden steel NAK80 from a temperature of 880-900oC followed by oil quenching. Hardness after quenching is 41 HRC.
Age-Hardening
Heat up to 550oC with heating speed 60oC/h, then hold 5 hours at temperature and then cool slowly in the air.7. Stability
