Four problems in the use of weathering boards

1.Solder joint corrosion: the oxidation rate of solder joints must be the same as other materials, requiring special welding materials and processes.

2. Water corrosion: weathering steel is not stainless steel. If there is water in the groove of weathering steel, the corrosion rate there will become faster, so it must be drained.

3.Salt-rich air environment: Weathering steel is as sensitive to salt-rich air environment as Hawaii. In this environment, the surface protective film may not be able to prevent further internal oxidation.

4.Fading: The rust layer on the surface of weathering steel will rust the surface of objects near it.

The weathering plate has the characteristics of strength, plastic extension, molding, welding and cutting, abrasion, high temperature and fatigue of high-quality steel; The weather resistance is 2 to 8 times that of ordinary carbon steel, and the coating property is 1.5 to 10 times that of ordinary carbon steel, which can be used thinly, exposed or simplified. The steel has the characteristics of rust resistance, corrosion resistance and prolonging life of the component, thinning and reducing consumption, saving labor and energy, benefiting the component manufacturers and users. Weathering steel products for the manufacture of containers, railway vehicles, oil derricks, harbor buildings, oil platforms and chemical and petroleum equipment containing corrosive media containers and other structural parts.
