ASTM A182 F317 Stainless Steel Flanges

Stainless Steel 317L Flanges are made up of an austenitic stainless steel with 18% chromium and 11% nickel in the composition along with carbon, silicon, manganese, phosphorus and up to 4% molybdenum in the composition. The Stainless Steel 317 Blind Flanges have more corrosion resistance than the 316 material made flanges. The blind flanges can come in different types but the most purpose is to close a connection.

The ASTM A182 Stainless Steel 317 Flanges come under different standards, dimensions and in different specifications. The specifications are ASTM A182 and ASTM A240. The standards range as ANSI B16.5 and B16.47. The sizes of the flanges range from ½ inches to 48 inches. There are different types of faces to the flanges such as the SS 317L Ring Type Joint Flange, flat face or raised face flange. The raised face flange has an outward flared raised face for more connection surface. The ring type joint has a groove on the face where a ring can sit. This allows for the compression of the ring during connection and makes it leakproof. The SS UNS S31700 Slip on Flanges are one of the functional types where there are welded neck flanges, orifice flanges, square flanges, reducing flanges and so on. The flange production can also range as threaded, forged, screwed or plate. The SS 317 Threaded Flange has threads on it where the pipes can be connected with threads. The flanges have female threads onto which the male threaded pipe ends will fit.
