Customized High Strength Flange Welding Nut M8 Hot Dip Galvanized

Customized high-strength M8 hot-dip galvanized flange welding nut.

Description

Welding nut is the material (same or different) of the workpiece to be welded. It is by heating or pressurizing or both, and with or without filling material, the material of the workpiece can reach the atomic construction and form a permanent connection.

Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to first pickle steel parts. In order to remove iron oxide on the surface of steel parts, after pickling, it is cleaned in a tank with ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride , And then sent to the hot dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Advantage
1. The entire surface of the steel is protected. The molten zinc can be easily and evenly covered regardless of the inside of the pipe fitting in the depression or any other corners where the coating is difficult to enter.

2. The hardness value of the galvanized layer is larger than that of the steel. The uppermost Eta layer has only 70 DPN hardness, so it is easy to be dented by collision, but the lower Zeta layer and delta layer have 179 and 211 DPN hardness values ​​respectively, which are higher than the 159 DPN hardness value of iron materials, so its impact resistance and The abrasion resistance is quite good.

3. In the corner area, the zinc layer is often thicker than other places, and has good toughness and abrasion resistance. The other coatings are often the thinnest and most difficult to apply at these corners, and the most vulnerable, so they often need to be maintained.
