SK is our material thickness less than 0.1mm ultra-thin spring steel strip. In addition, tolerance, such as thickness and hardness tolerance is proud of the high quality of the industry. SK is a lot of material to heat treatment before or after the treatment is very common. Material of the SK Corporation, Japan has gained the reputation of our customers, and an ideal product to maintain the best condition, dyed black paint to the surface roughness after the heat treatment.

 

The uses for:

 

Dot matrix printer, gaskets, sock machine needles, various leaf spring

Select metal advantage Oushi Bang:

Has a very high SK spring steel series quality, improve the organizational composition and adjustment of components due to strict management control.

100-500 kg of small quantities.

You may notice we adjust hardness according to production requirements.

Thin materials can be produced.

Can produce tiny thickness tolerances: Most materials can be made more precise thickness tolerances can be guaranteed.

To complete the (Satin mode) and surface (smooth) bright surface of the surface state is possible.

Carbon tool steel

Japan's Sumitomo spring steel

SK2, SK4, SK5, SK6, SK7

 Carbon tool steel, special polishing strip, has been the most widely used workability, hardenability, product performance, price.

Applications include the toughness and flexibility you need to spring, spring, needle knitting, speakers, tape measure, like the legend from the hard cutlery, cutting tool, the washing machine as a tool has been used in various fields.

 

Complete a variety of special spring steel strip steel, has been provided (completed or rolled back finishing), we, until the finishing strength since the completion of the annealing soft the hardest countries and regions of production requirements, you can choose the most suitable to complete your the purpose of the state.

Organize the state, is an ever-rolling in this way, for convenience, we have divided into several supply status in the table below. Although there are some kinds of steel, size differences, only as a guide for reference.
