ASTM A213 TP347 Stainless Steel Cold drawn Seamless Boiler and Heat-Exchanger Tubes
The SA213 Tp347 Cres Tubing also illustrates good resistance to corrosion by oxidation. In environments that contain strong oxidizing agents at elevated temperatures up to 1500°F, the 347 Seamless Tubing may rival the performance of its fellow austenitic stainless steel grade 321. Being one of the leading 347 Stainless Steel Tube Suppliers, we offer the most competitive pricing for these tubes. Aside from performing tests like hardness test, flattening test, Tension test and flaring tests, every 347 Stainless Tube produced under the ASTM A213 specification is required to undergo either a nondestructive electric test or a hydrostatic test. Austenitic specified ASTM A213 Tp347 alloys are designed to be used in applications involving superheater, steel boiler, and heat-exchanger tubes.
Delivery Condition: Annealed and Pickled (AP), Polished, Bright Annealed (BA), Cold Drawn, MF
