ASTM A182 F304H Flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed.
ASTM A182 F304H is a specification standard developed by ASTM International for forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves and parts intended for high-temperature service. The "F" in ASTM A182 F304H indicates that the material is a forging specification. The "304H" specifically refers to the grade of stainless steel.
ASTM A182 F304H Flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal.
ASTM A182 F304H Flange Grade is the standard "18/8" stainless; it is the most versatile and most widely used Stainless Steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. For these applications it is common to use special "304DDQ" (Deep Drawing Quality) variants.
Grade: ASTM A182 F304H specifies a High-Carbon variant of the popular 304 stainless steel. The "H" stands for high carbon content, making it suitable for high-temperature applications.
Chemical Composition: ASTM A182 F304H has a chemical composition that includes chromium, nickel, manganese, silicon, sulfur, phosphorus, carbon,Copper Nickel and nitrogen, among other elements. The high carbon content enhances the material's high-temperature strength.
Heat Resistance: The high carbon content in ASTM A182 F304H enhances its ability to withstand elevated temperatures. This makes it suitable for applications in industries where high-temperature resistance is crucial.
High-Temperature Service: ASTM A182 F304H flanges are commonly used in applications involving high temperatures, such as in the petrochemical, chemical, and power generation industries.
Weld Neck Flange, Slip-On Flanges, Blind Flange, Socket Weld Flanges, Lap Joint Flanges, Threaded Flanges: ASTM A182 F304H flanges are available in various types to suit different piping requirements and configurations.
ASTM International: The specification is developed and maintained by ASTM International, ensuring that products meeting the standard are of high quality and reliability.
Identification: ASTM A182 F304H flanges are typically marked with relevant information such as material grade, heat number, and manufacturer's identification. They may also come with certification to guarantee compliance with industry standards.
Quality Assurance: ASTM A182 F304H Flanges undergo various tests, including chemical analysis, mechanical testing, and non-destructive testing, to ensure their integrity and performance.
ComponentsASTM A182 F304H flanges are designed for use in high-temperature applications, providing excellent strength and corrosion resistance. Users should always refer to the specific requirements of their application and consult the ASTM A182 F304H standard for detailed specifications.
