321 stainless steel is an austenitic stainless steel characterized by excellent corrosion resistance at room temperature, as well as good high-temperature strength and creep resistance.
321 stainless steel bars have superior processing and welding properties, making it easy to perform cutting, bending, welding and other processing operations. Mechanical properties such as tensile strength, flexural strength and elongation are also excellent enough to meet the requirements of use in various complex environments. 321 stainless steel bars have excellent corrosion resistance and high temperature performance, so they are widely used as manufacturing parts in petroleum, chemical industry, aviation, and aerospace. 321 stainless steel bars can effectively resist corrosive media such as acids, alkalis, and salts and ensure the long-term stable operation of the equipment In the petroleum and chemical industries. In the aviation and aerospace fields, 321 stainless steel bars have become one of the important structural materials due to high operating temperatures and the requirement for materials with good creep resistance.
