Description

Products Details

High Carbon Steel Spring Wires have the characteristics of stable chemical composition, small deviation,uniform cleaning rod performance, high rate sorbitizing, good plasticity. High carbon steels are difficult to weld because they contain carbon in the range of 0.6 percent to 1.0 percent. High carbon steels are susceptible to heat, and it easily flame hardened which allows it to be worked into many different forms. High carbon steels have greater tensile strength and are used to create products where strength is required.

Application: for general application spring and mechanical spring.
Beside to make the wire according to the standard, we also try to supply the wire according customer's
special requirement.

Technical specification:
(1)Standard: DIN17223-1-1984,EN10270-1,ASTM-A227,GB4357-89
(2)Size: 0.20mm-14.0mm

1. General introduction:
Raw material is rigorously selected and approved before put into processing 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.
