201 stainless steel DIN929 spot welding nut M3M4M5M6M8M10M12.
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.
201 stainless steel has certain acid and alkali resistance, high density, no bubbles, no pinholes, etc. It is used to produce high-quality materials for various watch cases and watchband back covers. Mainly used to make decorative tubes, industrial tubes, and some shallow stretched products.
Zinc plating
There is a thick and dense pure zinc layer covering the surface of the steel fasteners, which can prevent the steel substrate from contacting any corrosive solution and protect the steel fastener substrate from corrosion. In the general atmosphere, a thin and dense zinc oxide layer is formed on the surface of the zinc layer. It is difficult to dissolve in water, so it has a certain protective effect on the base of steel fasteners. If zinc oxide and other components in the atmosphere form insoluble zinc salts, the anti-corrosion effect is more ideal; it has a zinc-iron alloy alloy layer, which is densely combined, and exhibits unique corrosion resistance in marine salt spray atmosphere and industrial atmosphere; due to the combination Strong, zinc-iron is mutually soluble, and has strong wear resistance; because zinc has good ductility, its alloy layer is firmly attached to the steel matrix, so hot-dip galvanizing can be cold punched, rolled, wire drawn, bent, etc. The forming process does not damage the coating; after the steel structural parts are hot-dip galvanized, it is equivalent to an annealing treatment, which can effectively improve the mechanical properties of the steel matrix, eliminate the stress during the forming and welding of the steel parts, and is beneficial to the turning of the steel structural parts; The surface of the fasteners after dipping galvanized is bright and beautiful; the pure zinc layer is the most plastic galvanized layer in hot-dip galvanizing. Its properties are basically close to pure zinc and have good ductility.
