The corrosion resistance of stainless steel discs mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal organizational structure, and the main role is chromium. Chromium has high chemical stability, can form a passivation film on the surface of the steel, isolate the metal from the outside world, protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate.

The main raw material of stainless steel sheet is stainless steel coil, usually stainless steel coil produced by cold rolling or hot rolling process. Stainless steel coil in the production process may be stained with rust, oxide and other impurities, need to be removed by pickling process. Pickling ensures a clean and smooth surface for subsequent processes. Stainless steel coils can be cold rolled or hot rolled after pickling. Cold rolling is the process of passing the coil through the roller to make the desired thickness while improving the surface finish. Hot rolling is to roll the coil to the required thickness under high temperature conditions, which is suitable for the production of thick plates.

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
