347 / 347H Stainless Steel Flanges

We, Seamac Piping Solutions Inc., are manufacturer, supplier, and exporter of a variety of Flanges. SS 347/347H Flanges are one of the best-selling and demanded type of Flanges. Alloy 347 is a Columbium/Tantalum stabilized Austenitic Chromium-Nickel Stainless Steel which has excellent weldability features and properties than common standards Austenitic Steels. This grade has excellent corrosion resistance in the higher temperatures and hence suitable for temperature range 450-degree C to 900-degree C. This alloy has properties like high mechanical strength and offers long service life with excellent flexibility. Alloy SS 347H is a higher version of the composite 347, which contains 0.04 to 0.10% of Carbon. This additional Carbon enhances creep resistance for the higher temperature. These Alloys are mainly used for corrosive environments and in high temperatures applications.
