Metric Steel Din603 Hot Dipping Galvanizing Mushroom Head Carriage Bolt

Description:

Hot-dip galvanized bolt is the removal of rust after the bolt immersed in molten 500℃ metal zinc solution, so that the zinc layer attached to the surface of the bolt, for corrosion protection, is a very effective way of corrosion protection.Background generally more of a hot dip galvanized high strength bolt, to prevent oxidation of the purification bolt before immersion plating pot, to remove surface residue, need to put a layer of flux layer on the surface, dip, easy heating volatilization, the flux layer to the surface of fresh bolt direct contact with molten metal zinc, infiltration, dissolution, diffusion and chemical reaction, etc., in the form on the surface of the steel and attach a layer of molten metal zinc alloy layer, the formation of zinc coating after cooling.The hot dip galvanizing of high strength bolt can obtain a thick galvanizing layer, the thickness is generally not less than 80 microns, the corrosion resistance is good, and the zinc coating adhesion is good, and convenient for subsequent welding and coating process.
