Flange types include lap joint, socket weld, weld neck and UNS N08904 blind flanges. Blind flanges close the pipeline. There are different types of blind flanges for different applications. Stainless steel 904L pipe flanges have a minimum tensile strength of 490MPa and a minimum yield strength of 220MPa. Flanges come in different sizes ranging from ½" to 48". The pressure rating of the flange varies by size. These flanges are available in pressure classes 150 to 2500. 904l stainless steel flanges are available in different production types such as plate flanges, threaded, threaded or forged flanges. The surface type of the flange is also different, such as a flat convex surface and an annular connection surface. ANSI B16.5 SS 904L Pipe Flanges are used in power generation, heat exchangers, boilers, chemical, petrochemical, oil and gas, and petroleum industry applications.
Stainless steel 904l flanges are made of unstable austenitic stainless steel material. The composition of the material consists of 23% nickel, 19% chromium and carbon, silicon, copper, sulfur, manganese, phosphorus and 4% molybdenum. Flanges conform to ASTM A182 and ASTM A240 specifications. ASTM A182 F904L stainless steel flanges are highly corrosion resistant. They are particularly resistant to chloride ions, mild acids and oxidation. Therefore, these flanges can be used in sour water service, seawater, brackish water and marine applications.
ASTM A182 F904L flange definition
ASTM A182 is a standard specification for wrought stainless steel pipe flanges and stainless steel wrought fittings.
ASTM 182 is for pressure systems, including flanges, fittings, and similar parts conforming to a specified size or dimension standard such as the ASME Code.
ASTM A182 F904L Flange is an unstable austenitic stainless steel with low carbon content. This high-alloy stainless steel has copper added to improve its resistance to strong reducing acids such as sulfuric acid. 904L is non-magnetic and has excellent formability, toughness and weldability.
Stainless steel 904L flanges contain many expensive components such as molybdenum and nickel. Today, most applications using the 904L grade have been replaced by the lower cost duplex 2205 grade.
ASTM A182 F904L flanges are suitable for industrial, construction and transportation applications.
