Stainless Steel 321 Flanges are made up of a titanium stabilized austenitic stainless steel. The material has similar composition to the 304 material but with added titanium. This gives the flanges with extra corrosion resistance and strength. The Astm A182 Grade F321 Stainless Steel Flange comes under ASTM A182 and A240 specifications. The flanges range from ½ inches to 48 inches in size with varying diameters and wall thicknesses.

The difference in the dimensions cause for the different pressure ratings. The flanges can range from class 150 through class 2500 for pressure ratings. The ANSI B16.5 SS 321 Blind Flanges are one special type that they do not extend the pipeline. They close the line. There are different types of blind flanges depending on the requirement of maintenance, permanent closure or other use cases of the application. The 321 stainless steel flanges have high melting point of 1454 degrees Celsius and they can operate up to 870 degrees Celsius temperatures. The material also has 205Mpa minimum yield strength and 515MPa minimum tensile strength. The SS 321 Blind Flange can also come with different face types such as flat face, raised face or ring type joint. Each different face type has a different advantage. The ASME B16.5 Stainless Steel 321 Flanges are made as threaded, forged, screwed or plate flanges. These different types are used in different applications. The applications of these flanges range from oil and gas to chemical and petroleum industrial applications. These are also used in high heat applications such as heat exchangers, boilers and in power generation plants.
