Mold steel NAK80


The hardness of NAK80 is 370-400HB after heat treatment, which is suitable for high-performance injection molds that needs mirror polish and EDM. The processing performance of NAK80 is superior, and easy to do repair welding. After a long period of production, the NAK80 mold steel can still maintain precision, and also, the hardness of the surface is uniform as usual.


Features of NAK80:

1. High purity; uniform internal structure; good mirror polishing effect.

2. The section after the EDM process is smooth, the hardness remains unchanged, and easy to grind.

3. Excellent welding performance. The high temperature during the welding will not affect the hardness of the steel; Even proceeding age hardening after welding, irregular etch lines will not happen.
