321 Stainless Steel Plate Description

321 stainless steel, due to its titanium content, exhibits improved crack resistance during the welding process. Additionally, it offers favorable processing and welding properties, facilitating cutting, bending, welding, and other operations. Its mechanical properties, including tensile strength, flexural strength, and elongation, are excellent, meeting the requirements for use in diverse environments. With its exceptional corrosion resistance and high-temperature performance, 321 stainless steel finds widespread application in petroleum, chemical industry, aviation, aerospace, and other fields. In the petroleum and chemical industries, where corrosive media such as acids, alkalis, and salts are prevalent, 321 stainless steel effectively resists corrosion, ensuring the long-term stable operation of equipment. Moreover, in the aviation and aerospace sectors, 321 stainless steel has emerged as a crucial structural material due to high operating temperatures and the need for materials with superior creep resistance.
