Duplex Steel 2205 nuts are tough fasteners crafted from duplex stainless steel, which boasts a well-balanced mix of austenite and ferrite. This unique blend gives them impressive mechanical strength, outstanding resistance to corrosion, and enhanced durability, making them perfect for challenging industrial and marine settings. These nuts excel at resisting pitting, crevice corrosion, and stress corrosion cracking caused by chlorides, ensuring they hold up reliably in critical applications.

Typically, Duplex Steel 2205 nuts contain about 22–25% chromium, 4–7% nickel, 2–3% molybdenum, and nitrogen, all of which boost their corrosion resistance and mechanical performance. They deliver a tensile strength of roughly 620–850 MPa and a yield strength of around 450–550 MPa, along with excellent toughness, ductility, and fatigue resistance. The dual-phase microstructure also guarantees thermal stability and resistance to intergranular corrosion, making these nuts dependable under high-pressure and high-temperature conditions.
