321 Stainless Steel Pipe
321 Stainless Steel Pipe is a titanium-stabilized austenitic piping product derived from 304, with titanium addition effectively preventing intergranular corrosion and ensuring no performance degradation after welding. It maintains excellent mechanical stability at medium and high temperatures, retains good weldability, formability and machinability, and meets food-grade safety standards. With customizable calibers, wall thicknesses and surface finishes, it adapts to mild corrosive working conditions, serving as a reliable premium choice for industrial high-temperature piping applications with welding requirements.
