The composition of Duplex Steel 2205 Nuts includes about 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, which together create a duplex microstructure of ferrite and austenite. This unique blend offers outstanding tensile and yield strength, excellent resistance to pitting, crevice, and chloride stress corrosion cracking, along with good weldability and toughness. The material also retains impressive mechanical properties and oxidation resistance even at high temperatures.
