Carbon spring steel wire is made of high carbon and high quality carbon structural steel or carbon tool steel wire rod, and its chemical composition, gas content and non-metallic inclusion must be strictly controlled according to the use of the spring.

Hot dip galvanizing is an effective metal preservative, mainly used in various industries of metal structure facilities. The steel parts after rust removal are immersed in the molten zinc solution at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anticorrosion. Hot dip zinc is to immerse the steel member after rust removal into the molten zinc liquid at about 600℃, so that the surface of the steel member is attached with zinc layer. The thickness of the zinc layer is not less than 65μm for the thin plate below 5mm, and not less than 86μm for the thick plate above 5mm. So as to play the purpose of corrosion prevention.
