Duplex steel wire is made from a balanced austenitic-ferritic stainless steel alloy, typically containing chromium, nickel, molybdenum, and nitrogen. This composition provides high tensile and yield strength, excellent corrosion resistance, and superior toughness. Duplex steel wire maintains good fatigue resistance and dimensional stability under high stress, pressure, and varying temperatures. It is highly resistant to stress corrosion cracking, pitting, and crevice corrosion, making it suitable for both structural and precision applications in aggressive environments.
