ASTM A213 TP321 1.4541 Stainless Steel Seamless Bright Annealed Tube
A213 TP321 is a specification of heat exchanger tubes that are made from the 321 austenitic stainless steel. The A213 specifies pipe products for heat exchangers in different material grades, both the ferritic and austenitic steels. YUHONG Group is a supplier of all kinds of stainless steel pipes. The A213 TP321 material is special in that the composition includes titanium which reduces the density of the ASTM A213 TP321 and therefore making it lightweight.
