Duplex UNS S32205 Flange | ASTM A182 F60 Duplex 2205 Weld neck flange Slip on Flange
What Is Duplex UNS S32205 Flange?
Duplex UNS S32205 flange, also known as ASTM A182 F60 flange, is a high-performance stainless steel flange widely used in corrosive and high-pressure piping systems.
UNS S32205, commonly referred to as Duplex Stainless Steel 2205, contains a balanced microstructure of austenite and ferrite, providing excellent mechanical strength and superior corrosion resistance.
Duplex 2205 flanges are commonly manufactured according to ASME B16.5 standards and are available in various types including weld neck flanges and slip on flanges.
Because of their excellent resistance to pitting corrosion, crevice corrosion, and chloride stress corrosion cracking, ASTM A182 F60 flanges are widely used in offshore oil & gas, chemical processing plants, desalination systems, and marine engineering pipelines.

ASTM A182 F60 is a grade of duplex stainless steel that offers excellent mechanical properties, corrosion resistance, and weldability. It is commonly used in various industries for critical applications requiring high strength and resistance to corrosion in aggressive environments. The chemical composition of ASTM A182 F60 typically includes elements such as chromium, nickel, molybdenum, and nitrogen, which contribute to its exceptional performance characteristics.
ASTM A182 F60 flanges are forged from duplex stainless steel, a dual-phase alloy renowned for its combination of austenitic and ferritic microstructures.
A182 F60 also known as Duplex stainless 2205 (UNS S32205) is a chromium-nickel- molybdenum-nitrogen stainless steel. UNS S32205 has high strength and corrosion resistance at temperatures up to 316°C. UNS S32205 is a duplex grade with a ferritic-austenitic microstructure. The alloy consists of around 40-50% ferrite in the annealed condition.
UNS S32205 is a duplex , ferritic, austenitic with chromium of 22%, molybdenum of 3%, and nickel 5 to 6% alloyed stainless steel. It is the most widely used grade of duplex stainless steel
22 refers to 22% chromium,5 refers to 5 to 6% nickel content.
