What is the purpose of NAK80 die steel?

NAK80 is a pre hardened plastic die steel. The factory hardness can reach hrc37-43. It has good polishing performance and carving property, and good EDM performance. Used in mirror polishing mold, automobile parts EDM mold, thickness not more than 2 mm thin plate, high efficiency blanking die, blanking die and stamping die, various scissors, inlaid blade, woodworking blade, thread rolling die and wear-resistant slider, cold heading mold, thermosetting resin forming mold, deep drawing forming mold and cold extrusion mold.

NAK80, a patent steel of Japan Datong Steel Co., Ltd., is a pre hardened plastic die steel. The hardness can reach hrc37-43. It has good polishing performance and carving property, and good EDM performance. Used in mirror polishing mold, automobile parts EDM mold, thickness not more than 2 mm thin plate, high efficiency blanking die, blanking die and stamping die, various scissors, inlaid blade, woodworking blade, thread rolling die and wear-resistant slider, cold heading mold, thermosetting resin forming mold, deep drawing forming mold and cold extrusion mold.

Deep drawing die, cold extrusion die

Typical application examples

(1) Mirror polishing mold, anti dust, TV filter board, cosmetic box, precision wrinkle processing mold;

(2) Office automation equipment, auto parts EDM mold;

(3) Transparent products or products requiring finish, such as car roof lamp, refrigerator vegetable box, lighting and other transparent product mold.

Heat treatment process

The three-step process of "hot working forging forming quenching tempering" was adopted to produce NAK80 precipitation strengthening plastic die steel with hardness range of 37-43hrc. The pre hardening treatment process effectively solved the problems of long pre hardening treatment time and low production efficiency of die steel. Quenching and tempering specification: quenching temperature 840 ~ 870 ℃, tempering temperature 200 ~ 500 ℃, hardness 50 ~ 55HRC; gas nitriding specification: soft nitriding temperature 520 ℃, time 5h, surface hardness up to 750hv.

Reference brand

The reference grades of NAK80 plastic die steel are as follows: Hitachi Hitachi standard steel grade hpm50, daidonak80 of Japan Datong and AISI standard steel grade p21.
