Advance Fitting is a reputable manufacturer and exporter of 904L Stainless Steel Flanges, which are composed of a nickel chromium austenitic stainless steel containing at least 23 percent nickel and 19 percent chromium, as well as carbon, manganese, silicon, phosphorus, sulphur, copper, and 4 percent molybdenum. Advance Fitting is an industry-leading manufacturer and distributor of 904L Stainless Steel Flanges in a variety of diameters. The mix of nickel, chromium, and molybdenum gives the material excellent corrosion resistance and strength. Minimum yield strength of 220 MPa and minimum tensile strength of 490 MPa are among the mechanical criteria. The material's melting point is also fairly high at 1350 degrees Celsius. The Alloy 904L Blind Flange is utilised to permanently seal the pipe's end. This version of the 904 steel grade contains less carbon. Due to the carbide precipitation that occurs during welding, these flanges are simple to weld and shape without the risk of grain development and intergranular corrosion.


The SS 904L Plate Flange is equipped with a plate to provide more area for welding, bolting, and other attachment techniques. The flanges adhere to the ASTM B649 standard, as well as ANSI, ASME, DIN, and EN standards. These flanges range in size from 1/2 inch to 48 inches, and their pressure classes vary. The ASME SA182 SS 904L WNRF Flanges have a weld neck and a raised face. The pressure classes for these flanges range from 150 to 2500 and PN6 to PN64, and their necks and faces are welded for enhanced strength. These flanges are utilised in numerous industries, including the pharmaceutical, petrochemical, marine, sea water, and energy generation sectors. The SS DIN 1.4539 Nippo Flanges are utilised in heat exchangers, boilers, condensers, the paper and pulp industry, offshore oil drilling, and the production of chemical and seawater equipment. We offer a variety of SS UNS N08904 industrial flanges to accommodate any application.
