Stainless Steel 904L Flanges are made up of a nickel-chromium austenitic stainless steel which has 23% nickel and 19% chromium minimum in the composition with carbon, manganese, silicon, phosphorus, sulfur, copper, and 4% molybdenum. The nickel chromium molybdenum composition provides the material with excellent corrosion resistance and strength. It also has good mechanical properties such as 220MPa minimum yield strength and 490MPa minimum tensile strength. The melting point of the material is also high at 1350 degrees Celsius. The Alloy 904L Blind Flange is used at the end of a pipe to close it, mostly permanently. 904L Material is a low-carbon version of the 904 grade of steel. This means welding and forming operations are easy on these flanges without risking grain formation and intergranular corrosion due to the carbide precipitation while welding.
Kalpataru Piping Solution is a leading supplier and manufacturer of Stainless Steel 904L Flanges in various categories. The SS 904L Flanges have a plate attached to them for a larger space to work with welding, bolting, and other attaching methods. Stainless Steel 904L Flanges come under ASTM B649 specification with various standards according to ANSI, ASME, DIN, and EN standards. The sizes of SS 904L Flanges range from ½ inches to 48 inches and the pressure classes vary. ASME SA182 SS 904L WNRF Flanges are welded neck-raised face flanges. SS 904L Flange has welded necks and raised faces, both for added strength and SS 904L Flange can range in pressure classes from 150 through 2500 and PN6 through PN64.
The application of SS 904L Flange is seen in a variety of industries including pharmaceutical, petrochemical, marine, seawater, and power generation. The SS DIN 1.4539 Nippo Flanges are used in heat exchangers, boilers, condensers, paper and pulp industries, offshore oil drilling, and chemical and seawater equipment manufacturing. We supply all types of the different SS UNS N08904 Industrial Flanges to suit any application. Please contact us for more product information and pricing.
904L Material has carbon, manganese, silicon, phosphorus, sulfur, chromium, molybdenum, nickel and copper. As a leading supplier of SS 904L Flange. The Class 150 ANSI SS 904L Flanges are a lower class of many pressure classes. There are pressure classes up to PN64.
The pressure classes are determined by the wall thickness and the nominal bore size of the flanges. There are different specifications such as the ASTM B649 UNS N08904 Flange. Some standards maintain the nominal bore sizes of SS 904L Flange. The ANSI B16.5 SS 904L Blind Flange falls under the B16.5 standard and the nominal bore sizes range from ½ inches to 48 inches.
