Applications
DIN 1. Tool steel is a plastic injection mould steel material, the steel by 'super clean' produce process, pre-hardened, showing the height of micro pure and excellent homogeneous structure, excellent polishing and light etching engraving. After heat treatment, processing and polishing performance is very good, can be carried out, and can be processed, suitable for the surface treatment of chrome, material hardness, good toughness, good mechanical processing performance. Gold microstructure is martensite and bainite structure. Main be applied to in plastic steel mold. like car injection moulding, PVC, PP plastic injection molding etc.

NAK80 1. P21 P20+S Hot Rolled Plastic Mould Steel
Quick Details
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.

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.
5. Heat Treatment of JIS Steel NAK80
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
6: Delivery condition
For hot forged bar, usually the delivery condition is hot forged, annealed/QT rough turned/Black surface.
For hot rolled bar, usually the delivery condition is hot rolled, annealed/QT, Black surface.
For hot forged plate, usually the delivery condition is hot forged, annealed/QT, milled surface
For hot rolled plate, usually the delivery condition is hot rolled, annealed/QT, black surface.
