M64 Hot Dip Galvanized Flat Washer

Product Description: Generally, hot dip galvanizing is to immerse the steel parts after rust removal into the plating tank of the zinc liquid melted at a high temperature of 455℃-560℃, so that the zinc layer is attached to the surface of the steel parts. Improve the corrosion resistance of metal surfaces. Hot dip galvanizing is the reaction of molten metal with iron matrix to produce alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is the first steel parts for pickling, in order to remove iron oxide on the surface of steel parts, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Application Industry: Widely used in automobile, construction, home appliances, chemical industry, machinery, petroleum, metallurgy, li…
