1.4462 stainless steel, also known as Duplex 2205, is a high-performance stainless steel alloy with a unique combination of excellent corrosion resistance, mechanical strength and toughness. The following introduces the main performance characteristics of 1.4462 stainless steel:

1.4462 stainless steel has excellent resistance to pitting, crevice and stress corrosion cracking, making it suitable for use in highly corrosive environments.
Containing a balanced composition of 22% chromium, 5% nickel and 3% molybdenum, the alloy offers superior corrosion resistance compared to conventional austenitic stainless steels.
1.4462 exhibits excellent resistance to a wide range of chemicals, including acids, chlorides and a variety of industrial environments, making it a first choice for applications in the chemical, petrochemical and marine industries.

1.4462 stainless steel has a unique dual-phase microstructure consisting of a balanced mixture of austenite and ferrite phases.
This dual-phase structure gives 1.4462 excellent mechanical properties, including high tensile strength (typically 620-860 MPa), high yield strength (typically 450-650 MPa), and good ductility and toughness.
The combination of strength and toughness makes 1.4462 suitable for applications where high mechanical loads, shock or vibration are present, such as structural components, piping systems and equipment frames.

1.4462 stainless steel maintains its mechanical properties and corrosion resistance at temperatures ranging from low temperatures to high temperatures up to 300°C (572°F).
This thermal stability is particularly beneficial for applications involving temperature fluctuations or exposure to moderately high temperatures, such as heat exchangers or industrial processing equipment.

1.4462 stainless steel can be easily welded using a variety of techniques, including TIG, MIG, and Stick Arc Welding (SMAW).
The material’s good ductility and formability make it easy to fabricate, including bending, rolling and machining, to produce a variety of structural components and shapes.
This manufacturing flexibility enables the design and construction of complex structures and equipment using 1.4462 stainless steel.

1.4462 stainless steel exhibits mild magnetic properties due to its dual-phase microstructure (containing both austenite and ferrite phases).
This magnetic behavior may be advantageous in certain applications, such as in the manufacture of magnetic components or the design of electromagnetic shielding systems.

Overall, 1.4462 stainless steel is a high-performance alloy that offers an excellent balance between corrosion resistance, mechanical strength, and thermal stability, making it a versatile choice for a variety of industrial applications, especially in in the chemical, petrochemical and marine industries.
