Steel copper-plated high-resistance salt spray internal thread welding pin.
Welding pin is a kind of high-strength rigid connection fasteners. Welding pins are cylindrical heads for arc stud welding, which is short for Cheese head studs for arc stud welding. The specifications of welding pins are nominal diameter Ф10～Ф25mm. The length is 40～300 mm. Welding pins have the manufacturer's identification mark made by embossing on the top surface of the head, and the welding pins have a wide range of uses.
Acetic acid salt spray test (AASS), copper accelerated acetic acid salt spray test (CASS)
They are all improvements to the neutral salt spray test. The test conditions are relatively close to the natural atmosphere, the test conditions are stable, the reproducibility is good, and the test cycle is short. It is suitable for the corrosion resistance test of the cathode coating. The principle is that the sodium chloride solution is sprayed after acidification with acetic acid to accelerate the corrosion rate, and is used for the corrosion resistance test of copper, nickel, and chromium plating on the steel substrate.
Copper accelerated acetate spray test (CASS), copper chloride is added to the solution of the acetate spray test. Due to the presence of Cu2+ in the test, the salt spray of the acidified copper-containing sodium chloride solution has cathodic effects on nickel, chromium, etc. The coating has a significant corrosive effect, and the test results are close to the corrosion of the urban atmosphere. It is suitable for copper, nickel, chromium plating or nickel and chromium plating. For example, the logo on the car, the chrome-plated outer handle, the chrome-plated inner handle, the chrome plate of the front grille, the chrome wheel nut and so on.
