The Duplex Steel Check Valves produced in Texas are made from a well-balanced mix of about 22% chromium, 5–6% nickel, and 3% molybdenum, along with some nitrogen, manganese, and silicon. This unique chemical composition boosts both corrosion resistance and mechanical strength. These valves showcase a tensile strength of around 620 MPa, a yield strength of 450 MPa, and impressive elongation and impact toughness. Such characteristics guarantee reliable performance in high-pressure, high-temperature, and corrosive settings, blending the best features of ferritic and austenitic steels.
