The galvanized spring steel wire

• As we all known, spring steel wire is easily to corrosion which will affect the work of the spring. There is different news about the unable use of the equipment caused by the corrosion of spring. The corrosion of spring steel wire can be divided into chemical corrosion and electrochemical corrosion according to the reaction of spring.
• During the spring steel wire’s manufacture and storage, it is often subject to the corrosion of the surrounding medium. As spring works by the elastic which will change and lose its function after the corrosion, prevent the corrosion of spring steel wire can guarantee the stable work of the spring and extend the service life. Metal protection layer is one of the surface treatments to prevent the spring corrosion.
• The general surface treatment used in the spring steel wire is the electricity metal plating layer. The electricity metal plating layer can not only protect against the corrosion, but also improve the appearance of spring. Galvanized spring steel wire is one of the spring materials with metal protection layer.
• The physical properties of galvanized spring steel wire are followed: the surface is smooth, has no crack, no thorn and no scar and rust; the galvanized layer is very uniform; the corrosion resistance is lasting; the toughness and elasticity are excellent; the tensile strength of galvanized spring steel wire is between 900Mpa to 2200Mpa.

Galvanized spring steel wire is a best choice for you if you are going to use the steel wire under normal atmospheric conditions.
