Stainless Steel 304L Flanges

Stainless Steel 304L Flanges are made up of the basic 18-8 stainless steel material that has 18% chromium, 8% nickel, carbon, silicon, sulfur, manganese and phosphorus in the composition. The material has good strength and low corrosion resistance. The 304L Stainless Steel Slip on Flanges are made under different specifications and dimensions according to different standards.

The slip on flanges are used in systems with seamless pipes where the pipes are allowed to slip onto the flanges. The ANSI 304L SS Flanges come under the ASTM A182, A240 specifications which are intended for high temperature and high pressure services. The standards vary as ANSI, ASME, DIN and other international standards. The dimensions are governed by ANSI B16.5, ANSI B16.47 and so on. The sizes of the SS 304L Pipe Flanges range from ½ inches to 48 inches and there are different pressure classes to the flanges. The different types of flanges are also used in different applications. The Stainless Steel 304L Blind Flanges are applied in a pipe to close the line. The connection can be permanently closed by welding or be temporary with bolting. The pressure classes of the ASTM A182 F304L Stainless Steel Flanges range from class 150 through class 2500 corresponding to the pressure numbers PN6 through PN64 with the pressure capacities up to 2500lbs. The Stainless Steel UNS S30403 Flange low carbon content and has 485MPa minimum tensile strength, 170MPa minimum yield strength and 201HB max Brinell hardness. The applications of the flanges are in many welding applications such as oil and gas, general corrosive applications, petroleum and other domestic applications as well.
