Heat Exchanger Tube ASME SA213 TP304 Stainless Steel Seamless Bright Annealed Tube
ASTM A213 TP304 Stainless Steel Seamless Bright Annealed Tube has the addition of nickel, nitrogen, manganese, which makes the steel have good weldability and formability. The corrosion resistance ability can be improved by augmenting the process. TP304 can be hardened by cold working process, retaining the strength and ductility. Our YUHONG GROUP is professional in manufacturing stainless steel seamless bright annealed tubes with high quality.
