About 347/347H Stainless Steel
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. Type 347H is a high carbon austenitic chromium stainless steel. Found in applications that demand high temperature resistance, other major design features include: Similar resistance and corrosion protection as Alloy 304.

A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flange joints are made by bolting together two flanges with a gasket between them to provide a seal. Flanges are commonly used to connect valves into pipework making it easier for removal and maintenance. There are many common flange standards and flanges within the same standard can either be flat (commonly cast iron, ductile iron) or raised face (commonly cast steel and stainless steel).
