NAK80, 1Ni3MnCuMoAl Advanced Prehardened Mirror Plastic Mold Steel- TJC STEEL.
 NAK80 is a senior mirror plastic die steel developed by Japan Datong Special Steel.10Ni3MnCuUAL is a similar type of steel developed and produced by China's steel mills on the basis of NAK80. It was officially [TJC STEEL]incorporated into the new national standard in 2014 and named as 1Ni3MnCumoal.

The performance characteristics of:

(1) After solid solution and aging hardening, the hardness reaches 37~43HRC;Uniform hardness of surface and core;Die processing directly put into use, without heat treatment;Low deformation in use can ensure high[TJC STEEL] precision.

(2)The polishing performance of the mirror is very good, and satisfactory brightness can be obtained.

(3)The discharge machining performance is excellent.Machining surface hardness does not rise, easy to precision[TJC STEEL] machining;The processed surface is compact and beautiful, which can replace pear skin erosion.

(4) Excellent welding performance.The hardness of the welding place is not increased;After welding, aging treatment will not produce uneven erosion.

 

Applications:

NAK80 is the representative steel of 40HRC grade prehard plastic die steel.It is often used in the manufacture [TJC STEEL]of mirror plastic molds with high requirements for appearance quality, and for the production of transparent plastic parts and all plastic products with mirror requirements.
