style=\"font-family: Arial; letter-spacing: 0px; font-size: 14px;\">321 stainless steel has better crack resistance during the welding process due to the titanium content. \u00a0 \u00a0In addition, 321 stainless steel also has good processing and welding properties, making it easy to perform cutting, bending, welding and other processing operations. \u00a0 \u00a0Its mechanical properties such as tensile strength, flexural strength and elongation are also excellent, and can meet the requirements of use in various complex environments. \u00a0 \u00a0Because 321 stainless steel have excellent corrosion resistance and high temperature performance, they are widely used in petroleum, chemical industry, aviation, aerospace and other fields. \u00a0 \u00a0In 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 can effectively resist the corrosion of these media and ensure the long-term stable operation of the equipment. \u00a0 \u00a0In the aviation and aerospace fields, 321 stainless steel has become one of the important structural materials due to high operating temperatures and the requirement for materials with good creep resistance.<\/span><\/p>\n<p style=\"text-indent: 0px; background: #ffffff; text-align: center;\"><img alt=\"\"
