321 stainless steel pipe (UNS S32100) is a titanium-stabilized austenitic stainless steel pipe derived from 304 stainless steel, with titanium added to suppress intergranular corrosion caused by chromium carbide precipitation. It excels in high-temperature resistance, corrosion resistance, and mechanical stability.
