Before getting to know the 300 series stainless steel coil, let us first understand what is 300 series stainless steel. 300 series stainless steel is a class of austenitic stainless steel, the main alloying elements include chromium and nickel. It has excellent corrosion resistance and can resist the attack of oxidative, acidic, and alkaline media.
The 300 series stainless steel coil is a thin and long coil product made of 300 series stainless steel. The production process includes multiple processes such as raw material heating treatment, hot rolling or cold rolling process, deviation correction, and shearing. These coils have the advantages of good corrosion resistance, high strength, easy maintenance, and beautiful appearance.
It is widely used in construction, food processing, catering equipment, and other fields, and is used to manufacture storage tanks, pipelines, food processing equipment, and other industrial equipment that require corrosion resistance and high temperature.
