Duplex Steel S32205 Pipes

About Duplex Steel S32205 Pipes

Duplex Steel 2205 is a two-phase stainless steel composed of about equal parts austenite and ferrite. It is also known as UNS S32205, EN 1.4462 and ASTM 2205 in the industry. This grade offers outstanding corrosion resistance, high tensile strength, and resistance to stress corrosion cracking, making it a preferred choice for demanding environments such as oil & gas, chemical processing, desalination, and marine applications. It offers a significant cost advantage without compromising performance, as it contains less nickel than standard austenitic grades.

Outstanding Mechanical Performance

Duplex Steel S32205 Pipes stand out for their exceptional combination of strength and ductility, making them particularly suitable for high-stress environments. The material features a minimum yield strength of 450 MPa, minimum tensile strength of 620 MPa, and a guaranteed elongation of at least 25%, ensuring resilience and performance even during rigorous bending or welding operations.


Exceptional Corrosion and Heat Resistance

Engineered with an advanced chemical composition that includes 22% chromium, 5.5% nickel, and 3% molybdenum, these pipes deliver excellent resistance to intergranular and pitting corrosion. The pipes maintain reliable service at temperatures up to 300C, making them suitable for both high-temperature and harsh chemical environments such as power plants and petrochemical refineries.


Versatile Applications and Customization

With customizable diameters (6 mm to 630 mm), thicknesses (1 mm to 30 mm), and lengths, Duplex Steel S32205 Pipes cater to a wide spectrum of industry requirements. Available with plain, beveled, or threaded ends, and various finishes, they are an optimal solution for fluid transmission and structural applications, efficiently meeting project-specific demands in construction, marine, and energy sectors.
