1. General introduction:
Raw material is rigorously selected and approved before put into processing while five main chemical compostion results shown as below:
C | Si | Mn | P | S |
0.40-1.00 | Max 0.35 | 0.30-1.50 | Max 0.04 | Max 0.04 |
Conventional technique integrated with modern leading-edged equipment makes our finished products shines on comprehensive functioning and performance when adoped. For serving spring and wire form industry, high tensile strength is not the ultimate goal to pursue, but the balance of flexibility and tensile strength to prevent our wire from deformed or broken up during winding in spring machine. In addition, for other usage, our products also have gained a sound reputation from the appliance as controlling cable or connecting wire for automobile industry and hard needle. Hot-dipped and electro-galvanized spring wire available.
