347 Stainless Steel Pipes and 347H Stainless Steel Tubes is type of common austenitic stainless steels such as 304, 316 and 321 and are widely used in elevated temperature applications.
Stainless steel 347 has excellent forming and welding qualities, and the addition of columbium and tantalum helps for exceptional intergranular corrosion resistance. Alloy 347H is the higher carbon variant of the alloy, enabling enhanced creep resistance and for higher strength at temperatures above 537°C.

SS 347 Pipes is similar to grade SS 321, but with slightly improved corrosion resistance in strongly oxidizing environments. Also referred as WNR 1.4550 and WNR.1.4961 Stainless Steel Welded Tubes, they are essentially non-magnetic in the annealed condition and can only be hardened by cold working.
Commonly known as UNS S34700 and UNS S34709, these Stainless Steel 347 Pipes & Stainless Steel 347 Tubes are popularly used in petroleum refineries, aircraft engine components, power generation, heat exchangers, pressure vessels, welded fabrications and other high heat applications.
