4,  galvanized can be used zincate galvanized or chloride galvanized process, should use appropriate additives to meet the requirements of this standard coating.

1, stress relief before plating where the maximum tensile strength is greater than 1034Mpa key and important parts before plating should be at 200±10℃ stress relief for more than 1 hours, carburizing or surface quenching parts should be at 140±10℃ stress relief for more than 5 hours.

The spring operating at high temperature requires that it can adhere to the elastic limit and good creep resistance at high temperature. In addition, the forming process and heat treatment process of spring steel wire should also be considered. Cold drawn spring steel wire and oil quenched tempered spring steel wire are directly around the supply of steel wire spring, spring forming after the elimination of stress directly used.
