What is a Stainless Steel 347 Flanges ?

Stainless Steel 347 Flanges are using grade 347, which is similar to the 321 stainless steels in that it is often used as a stabilized alternative to Type 304. In the case of 347, however, the stabilizing agent is columbium. This metal intensifies 347’s already present ability to withstand intergranular corrosion for maximum capabilities. Additionally, the columbium allows for 347 to undergo repeated heating in temperatures up to 1650° F. As a result, the metal is commonly applied to high temperature equipment, such as gaskets and expansion joints, along with rocket engine. In addition to its heat resistance properties, SS 347 Slip on Flanges also have better resistance against creep and stress rupture corrosions. This is another advantage of type 304, as 347’s characteristics may be better suited for environments where stabilization is a primary concern.
