Super Duplex Steel Square Bars consist of about 25% chromium, 7% nickel, 3–4% molybdenum, and nitrogen. This unique alloy features a mixed austenitic-ferritic microstructure that delivers outstanding strength and corrosion resistance. The material showcases a tensile strength ranging from 750 to 1000 MPa and a yield strength of around 550 MPa, along with impressive fatigue and impact resistance. It also offers excellent protection against stress corrosion cracking, pitting, and crevice corrosion, especially in harsh environments like seawater or acidic process streams. These bars maintain their strength and toughness even in extreme temperatures, both high and low.
