Taixing Hongye Steel Wire Products Co., Ltd has been purchasing Shagang's steel wire rods.In recent years, Shagang`s products have been exported to East Asia, South Asia, Europe, America, Oceania, Africa and more than 80 countries and regions.Their quality is very good.

Cold Drawn Steel Wire is made of Shagang wire rod. 

There are many kinds of the usages of Spring Steel Wire.

Such as:Compression spring,torsion spring,extension spring,agricultural machines,die springs,strip&wire forming springs

High Carbon Spring Steel Wire diameter is range from 0.20mm to 12.50mm.

The production process of Carbon Steel Wire is roughly divided into 4 parts:

firstly,removing the oxide that layer on the wire rods;next it is hydrochloric acid cleaning phosphating,;saponification;and drawing wires ; 

After production, we can do tensile strength test,reduction of area test,elongation test,torsion test,wrapping test ,bending test,ect.to test the quality of the product.
