ASTM A213 TP 321 Seamless Stainless Steel Tube

A213 TP 321 Seamless Stainless Steel Tube

We manufacture ASTM A213 TP 321 seamless stainless steel tube, seamless tubes finished with both annealing pickling and pickling finishes, there is a large range of tube sizes and dimensions to be offered, and dimensional tolerance should be tight and exact, wall thickness tolerance is plus tolerance in minimum thickness unless average wall thickness required.

ASTM A213 TP 321 seamless tube is made from stainless steel billet, after cold drawn and cold rolling, heat treatment should be made in specific temperate, finished seamless tubes are mainly applied for boiler, heat exchanger, superheater system.

ASTM A213 TP321 Stainless Steel

TP321 stainless steel is CR-NI-TI an Austenitic steel, it has excellent high-temperature stress properties and mechanical properties, its properties are similar to stainless steel 304, but 321 is better than 304 in many aspects, the addition of the Ti element improves intergranular corrosion resistance, and high temperate resistance, 321 stainless steel has good performance in Stress Rupture and Creep Resistance.
