SS 347 / 347H High Temperature Austenitic Stainless Steel Pipe With UNS S34700 DIN 1.4550 For Boiler Tube

A312 TP347 material is stabilized against chromium carbide formation by the addition of columbium and tantalum. 347 Stainless Steel Pipe is non-magnetic alloy. 347 Tubing is stabilized by the addition of columbium and tantalum. SS 347 Tubes offers higher creep and stress rupture properties than SS 304. 347 Seamless Pipe also performs better in strongly oxidizing environments up to 1500°F (816°C). A312 Gr TP347 Pipe are suitable to use in nitric solutions, most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10% diluted solutions at elevated temperatures.
