Use range


Generally used in the mirror polishing mold, anti-dust, TV filter, cosmetics boxes, precision wrinkles processing molds, office automation equipment, auto parts EDM mold.

 

Transparent products or products that require smoothness, such as household products, automobiles, cameras, computers and other products on the transparent mold.


● Thickness of not more than 2MM thin sheet, high-efficiency blanking die, die and die impulse mode.
● various scissors, inserts, woodworking blade.
● Thread rolling die and wear-resistant slider.
● cold heading die, thermosetting resin molding.
● Deep drawing die, cold extrusion die

 

 

Characteristic


1. Pre-hardened steel, without any heat treatment (factory state: age hardening, HRC37 ~ 42 ℃);
2. The most suitable for pre-polished steel mirror processing;
3 discharge machining characteristics:
4. ① after treatment of the surface is very good, can replace the etching processing;
4. ② in the discharge (EDM) processing, the surface hardness will not increase, which can simplify the subsequent processing steps.
5. Good weldability, surface scraps will not be hardened, which can simplify the subsequent process;
6. Toughness, excellent mechanical properties, reduce the fear of rupture and other issues.

 

 

Grinding processability


than other steel easy to reach the mirror requirements, because of the following two points:


1) Minimize pinholes due to double melting and refining.
2) Because it is low-carbon precipitation hardened steel, but with a detailed and uniform microstructure. Before grinding and polishing, the surface must first achieve the required flatness, straightness, and the correct shape and size.

 

 

Performance comparison


In addition to the various features of the NAK55, the has the following features:


1, Mirror grinding is extremely good.
2, EDM surface meticulous, beautiful, therefore, can replace pears eclipse flowers.

 

 

Use comparison


compared with the NAK55, suitable for the following performance occasions:


1, Transparent products, such as emphasis on mirror grinding
2, Pay attention to the EDM surface
