347H stainless steel pipe spool 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 347H pipe spool has a good mechanical properties welding performance, excellent resistance to intergranular corrosion .

Stainless Steel 347H Pipe Spools are made from an austenitic stainless steel alloy containing chromium, nickel, and other elements. It is known for its excellent corrosion resistance, even under extreme temperatures, by forming a thin oxide layer on its surface. This oxide layer protects the pipe from exposure to water and other environmental conditions. The addition of niobium in the Stainless Steel 347H improves intergranular corrosion resistance, meaning that welds are less likely to corrode or fail prematurely due to the presence of aggressive substances in the environment. The high creep strength also makes these stainless steel pipe spools ideal for applications with elevated temperatures ranging between 800°C – 1100°C (1472°F – 2012°F). As such, these welded pipes are used in industrial boilers, pressure vessels, power generation plants, and energy conversion systems like heat exchangers, among others.
