Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the EN10025 S690QL steel, stainless steel from corrosion.

During the welding of hardfacing wear-resistant steel plate, EN10025 S690QL steel, the welding shall be carried out in strict accordance with the drawing, welding process and relevant standards. Follow the welding sequence of first welding the base layer, then welding the transition layer, and then welding the multiple layer. In order to prevent adhesion of welding spatter, anti spatter coating should be applied within 100 mm on both sides of groove of stainless steel clad plate before welding.
