Alloy Steel F91 Flanges have very high durability, good dimensional accuracy, high tensile strength and very good anti corrosive properties. A182 F91 material is made up of an alloy that houses chromium and molybdenum mixture with chromium not less than 20%. Depending on the grade, the chromium content in ASTM A182 F91 Flanges could go up to 40%. This specific composition allows ASTM A182 Grade F91 Flanges to be very much oxidation resistant, crevice corrosion crack attack resistant and stress corrosion cracking resistant.

ASTM A182 F91 Pipe Flanges are used to fit the pipes of high grade stainless steel together. SA 182 Gr F91 Steel Flanges are delivered in a solid solution annealed condition which makes them to be precise, hard and workable in the applications.
ASTM A182 F91 Flanges come in different shapes, forms and grades for different needs. The Alloy Steel A182 Grade F91 WNRF Flanges are special in the way that they have an extra neck welded to them. This neck can differ in dimensions but it supports the connection with an additional cover. These are used in fairly high pressure connections where bending stress is eminent and the system could break at the connections. AS A182 F91 RTJ Flanges are different than the other types in the manner that they have a groove in the middle to hold a gasket through.
What is A182 F91 Flanges?

So when the ring type joint is tightened, the gasket gets into the groove and seals the gap completely. These types of flanges are used in connections where a joint has to be leak proof to extreme levels and in deviating temperatures. A182 F91 Alloy Steel Blind Flanges have a blind end and do not connect two pipes. They only add at the end of one pipe and end the connection. Since they have very low thermal expansion numbers and are very reliable under high temperatures, they can keep the opening sealed even at high temperatures. In applications where there are two pipes that need to be held in place due to a bending stress risk, A182 F91 Steel Slip On Flanges can be applied to hold the pipes inside the bore of the flanges.
