Product Detail

347H stainless steel pipe is a high carbon austenitic stainless steel pipe, with an excellent heat-resistance material which is applied to boiler, heat exchanger, car and aircraft exhaust, chemical equipment etc.

As a higher grade from AISI 321H, the intergranular corrosion of 347H is achieved through the use of niobium (Nb) as a stabilizing element to maximize this feature.  SS 347 has a good mechanical properties，welding performance, excellent resistance to intergranular corrosion .
