ASTM A213 TP321 Stainless Seamless Tube 16in X25.4mm 10-13m Length
ASTM A213 TP321 Seamless Tube Supplier
SA213 TP321 is a specification of heat exchanger tubes that are made from the 321 austenitic stainless steel. The SA 213 specifies pipe products for heat exchangers in different material grades, both the 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 making it lightweight.
The addition of titanium also provides the ASTM A213 Tp 321 pipes with high corrosion resistance properties. The intergranular corrosion risk present in most high carbon steels is reduced in the 321 Stainless Steel Tubing due to the addition of titanium. The 321 Stainless Steel Exhaust Tubing can last longer in high temperatures. Therefore the 321 Stainless Steel Seamless Tubing is used in heat exchangers and in super heaters. The application of the Type 321 Stainless Steel Tubing can also be seen in boilers and in condensers. We produce high quality 321 SS Tubing in different sizes and types. Our SS 321 Seamless Tubing is suitable for smaller size piping with high accuracy. Our customers can get custom finishes of these pipes as well. Please contact us with any of your inquiries on product details or pricing.
