ASTM A182 / ASME SA182 F321 UNS S32100 WNRF Stainless Steel Flanges
321 stainless steel is a high-strength, heat-resistant alloy that contains titanium to stabilize the material against chromium carbide formation during welding. This makes it suitable for applications where the flange will be exposed to high temperatures.
Forged flanges are made by the process of forging, which involves shaping the metal by applying pressure and heat. This results in a more robust and compact structure compared to other manufacturing methods. Forged flanges are commonly used in the oil and gas, petrochemical, and chemical industries, as well as in power generation and shipbuilding.

321 stainless steel forged flanges have several benefits, including:
High temperature resistance: The titanium stabilization in 321 stainless steel provides excellent resistance to intergranular corrosion and makes it capable of withstanding elevated temperatures up to 1500°F (816°C) without losing its mechanical properties.
Corrosion resistance: 321 stainless steel is resistant to a wide range of corrosive environments, including acidic and alkaline solutions, making it suitable for various applications where corrosion resistance is crucial.
Strength and durability: The forging process enhances the strength and durability of the flange, making it capable of withstanding high-pressure and high-temperature environments.
Weldability: Unlike some other stainless steel grades, 321 stainless steel is easily weldable, allowing for seamless integration into pipelines or equipment.
321 stainless steel forged flanges come in various types, such as weld neck, slip-on, blind, threaded, and socket weld flanges. These types have different designs and connection methods to suit specific applications.
Applications of pipe flanges
Pipe flanges are widely used in pipe fittings of various industrial, commercial and residential applications. Pipe flanges can be customized to suit your application with various machining details. These pipe flanges have been used extensively in:
UHV applications
A. Hydraulic control systems for turbine generators
B. High pressure ground support missile systems
C. Nuclear and conventional power plant applications etc.
