Duplex 2205 flanges are a type of flanges made from Duplex 2205, a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5-6% nickel alloy. This alloy is highly resistant to corrosion, especially in harsh environments, making it an ideal material for various industrial applications. The UNS S31803 and UNS S32205 are two grades of Duplex 2205.

UNS S31803 is a duplex stainless steel that combines high mechanical strength with excellent corrosion resistance. It has a microstructure consisting of equal proportions of austenite and ferrite phases, which provides good resistance to stress corrosion cracking and pitting corrosion. UNS S32205 is a higher grade of Duplex 2205 with improved mechanical properties, such as higher yield strength and better resistance to corrosion fatigue.

Duplex 2205 flanges are commonly used in applications that require high strength, good corrosion resistance, and resistance to stress corrosion cracking. They are widely used in the oil and gas industry, chemical processing, pulp and paper industry, marine engineering, and other applications where corrosive environments are present.

Duplex 2205 flanges are available in various sizes, shapes, and types, including slip-on, weld neck, blind, threaded, lap joint, and socket weld. They are also available in various standards, such as ANSI, ASME, ASTM, DIN, and EN. When selecting Duplex 2205 flanges, it is important to consider the specific requirements of the application, such as temperature, pressure, and corrosive environment.

Q: What is duplex stainless steel type 2205?
A: Duplex stainless steel type 2205, also known as UNS S32205/S31803, is a corrosion-resistant alloy that belongs to the duplex family of stainless steels. It combines the desirable properties of both austenitic and ferritic stainless steels, offering high strength, good weldability, and excellent resistance to corrosion and stress corrosion cracking.

Q: What is 2205 stainless steel used for?
A: 2205 stainless steel finds applications in various industries due to its unique properties. Some common uses include:

  1. Chemical processing equipment: It is resistant to corrosive chemicals, making it suitable for vessels, tanks, and pipes.
  2. Oil and gas industry: It is used in offshore platforms, pipelines, and components exposed to harsh environments.
  3. Marine applications: It is employed in shipbuilding, offshore structures, and propeller shafts.
  4. Desalination plants: Its corrosion resistance makes it ideal for use in seawater desalination plants.
  5. Structural components: It is used in bridges, pressure vessels, and storage tanks.
  6. Pulp and paper industry: It is utilized in digesters, bleach plants, and piping systems.
  7. Food processing: It is suitable for equipment exposed to acidic or chloride-containing food products.

Q: What is the difference between S32205 and 2205?
A: S32205 and 2205 both refer to the same duplex stainless steel grade. S32205 is the ASTM designation, while 2205 is the common industry name for the material. They have identical chemical compositions and properties, and the terms are often used interchangeably.

Q: What is the difference between duplex 2205 and 316 SS?
A: Duplex 2205 and 316 stainless steel (316 SS) are both stainless steels, but they belong to different families and have distinct characteristics:

  1. Composition: Duplex 2205 is a duplex stainless steel alloy, consisting of approximately 22% chromium, 5-6% nickel, 3% molybdenum, and other elements, such as nitrogen. In contrast, 316 SS is an austenitic stainless steel containing 16-18% chromium, 10-14% nickel, and 2-3% molybdenum.
  2. Corrosion resistance: Duplex 2205 offers higher resistance to localized corrosion, such as pitting and crevice corrosion, due to its higher chromium and molybdenum content. 316 SS is also corrosion-resistant but may be more susceptible to certain types of corrosion in specific environments.
  3. Strength: Duplex 2205 has significantly higher strength compared to 316 SS, making it suitable for applications requiring greater mechanical strength.
  4. Price: Duplex 2205 tends to be more expensive than 316 SS due to its enhanced properties and higher alloy content.
  5. Weldability: While both materials are generally weldable, duplex 2205 is known for its better weldability and lower risk of sensitization during welding.
