Here's a brief introduction to ASTM A182 F321 flanges:

321 stainless steel flanges are made from titanium stabilized austenitic stainless steel. This material has a similar composition to the 304 material, but contains titanium additives. This further increases the corrosion resistance and strength of the flange.

ASTM A182 F321 is a specification developed by ASTM International that covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves and parts for high-temperature service. Specifically, F321 is a grade within the A182 specification, indicating a specific type of stainless steel alloy.

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 F321 Flange (UNS S32100) is titanium stabilized austenitic stainless steel plate with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 - 1500°F (427 - 816°C). The alloy resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness. ASTM A182 F321H Flanges (UNS S 32109) stainless steel is the higher carbon (0.04 - 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000oF (537°C). In most instances, the Carbon Steel content of the plate enables dual certification.

Material Composition:

  • F321 is a stainless steel grade that belongs to the austenitic family, known for its corrosion resistance and high-temperature strength.
  • The chemical composition typically includes elements such as chromium, nickel, and titanium. The addition of titanium enhances the alloy's resistance to intergranular corrosion.


ASTM A182 F321 Flanges are commonly used in applications where corrosion resistance and high-temperature strength are crucial. They find extensive use in industries such as chemical processing, petrochemical, and power generation.

Flange Types:

Flanges covered by ASTM A182 F321 can be of various types, including welding neck, Slip-On, socket weld, lap joint, threaded, and Blind Flange, among others. Each type serves a specific purpose and is designed for particular applications.

Heat Treatment:

F321 undergoes a solution annealing heat treatment, which helps enhance its mechanical properties and corrosion resistance. The heat treatment also eliminates unwanted residual stresses.

Standards Compliance:

ASTM A182 F321 flanges are manufactured in accordance with the ASTM A182 standard, ensuring that they meet specific mechanical and chemical property requirements.

Corrosion Resistance:

The Stainless Steel Alloy F321 is particularly resistant to a wide range of corrosive environments, including acidic and chloride-containing environments. This makes it suitable for use in aggressive chemical and offshore applications.

Testing and Inspection:

F321 flanges undergo various tests, including chemical analysis, mechanical testing, non-destructive testing, and visual inspection, to ensure that they meet the specified standards and requirements.

Size Range:

ASTM A182 F321 Flanges are available in a wide range of sizes to accommodate different piping and Pressure Vessel requirements.When selecting ASTM A182 F321 flanges, it's essential to consider the specific requirements of the intended application, including pressure, temperature, and corrosive conditions. Compliance with ASTM standards ensures the quality and reliability of these Components in various industrial settings.
