321 Stainless Steel Coil is a titanium-stabilized austenitic stainless steel derived from 304, with titanium addition effectively preventing intergranular corrosion and ensuring no obvious performance degradation after welding. It has excellent mechanical stability at medium and high temperatures, good formability, weldability and machinability, and complies with food-grade safety standards. Suitable for medium-high temperature and mild corrosive working conditions, it’s a reliable premium choice for industrial high-temperature applications with welding requirements.
