Product Description

321 stainless steel has better crack resistance during the welding process owing to the titanium content. Besides, 321 stainless steel also has good processing and welding properties, which makes it easy to perform cutting, bending, welding and other processing operations. Its mechanical properties such as tensile strength, flexural strength and elongation are also outstanding, and can fulfill the requirements of use in various complex environments. Because 321 stainless steel coils have excellent corrosion resistance and high temperature performance, they are often used in petroleum, chemical industry, aviation, aerospace fields. In the petroleum and chemical industries, since the production process involves a large amount of corrosive media such as acids, alkalis, and salts, 321 stainless steel coil manages to resist the corrosion of these media and ensure the long-term stable operation of the equipment.
