Here is a brief introduction to ASTM A182 F309S flanges:

ASTM A182 F 309S threaded flanges are used on externally threaded pipes. Flanges usually have internal threads. We offer SS material No. 1.4833 socket welding flanges to weld the sockets as additional support.

ASTM A182 F309S is a specification for forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves intended primarily for high-temperature and corrosive service. The "F309S" designation specifically indicates that the material is a stainless steel alloy, and the "S" stands for the modification of the standard composition to enhance its resistance to corrosion.

ASTM A182 is the Standard Specification for Forged Stainless Steel Pipe Flanges and Stainless Steel Forged Fittings. ASTM 182 is use in pressure systems, Included are flanges, fittings and similar parts to specified dimensions or to dimensional standards, such as the ASME specifications. ASTM A182 F309s Flange Alloy 309 (UNS S30900) is an austenitic stainless steel developed for use in high temperature corrosion resistance applications. The alloy resists oxidation up to 1900°F (1038°C) under non-cyclic conditions. Frequent thermal cycling reduces oxidation resistance to approximately 1850°F (1010°C).

309S (UNS S30908) is the low carbon version of the alloy. It is utilized for ease of fabrication. 309H (UNS S30909) is a high carbon modification developed for enhanced creep resistance. It most instances the grain size and carbon content of the plate can meet both the 309S and 309H requirements.

Material Composition:

  • ASTM A182 F309S is a stainless steel alloy that contains high levels of chromium and nickel, which contribute to its corrosion resistance in high-temperature environments.
  • The alloy may also include other elements such as manganese, silicon, sulfur, phosphorus, and carbon to achieve specific mechanical and corrosion-resistant properties.


These flanges and Din Flanges are commonly used in applications involving high temperatures and aggressive corrosive media. Typical industries include petrochemical, chemical processing, power generation, and oil and gas.

Temperature Resistance:

The high chromium and nickel content in F309S provide excellent resistance to High-Temperature oxidation and corrosion, making it suitable for applications where elevated temperatures are a concern.

Manufacturing Standards:

ASTM A182 sets the standard for the forging or rolling process of these flanges. This specification covers dimensions, tolerances, and material requirements

Types of Flanges:

The ASTM A182 F309S specification includes various types of flanges, such as weld neck,Weld Neck Flange, slip-on, blind, socket weld, and threaded flanges, among others. Each type serves specific purposes and is designed for particular applications.

Testing and Inspection:

F309S flanges are subject to various tests to ensure their quality and adherence to standards. Common tests include chemical analysis, mechanical testing (tensile, hardness), non-destructive testing (ultrasonic, radiographic), and visual inspection.

Corrosion Resistance:

The modification "S" in F309S signifies additional resistance to corrosion, making it suitable for service in corrosive environments.

Marking and Certification:

ASTM A182 F309S flanges are marked with specific information, including material grade, size, pressure class, and other relevant details. Manufacturers often provide certification to validate compliance with the ASTM standard.

It's essential to refer to the specific requirements of the ASTM A182 F309S standard and consult with manufacturers or suppliers for detailed information regarding the use and characteristics of these flanges in specific applications.
