ASTM A213 TP321 Seamless heat exchanger austenitic stainless steel tube
SA213 Tp321 is a specification of heat exchanger tubes that are made from TP321 austenitic stainless steel. The SA 213 specifies pipe products for heat exchangers in different material grades, both ferritic and austenitic steels.
The SA213 Tp321 Material is special in that the composition includes titanium which reduces the density of the ASME SA213 Tp321 and therefore makes it lightweight.
