AISI 347 (1.4550, S34700) Stainless Steel Tubes| AISI 347H (1.4912, S34709) Stainless Steel Tubes
Grade 347/347H (UNS S34700/S34709, EN 1.4550/1.4912) is most widely used Austenitic stainless steel. Grade 347H is the higher carbon variant of the Alloy, 347/347H stainless steel is type of common austenitic stainless steels such as 304, 316 and 321 and is 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.
