Duplex Manifold Valves showcase a unique dual-phase microstructure, consisting of about 50% ferrite and 50% austenite, which gives them an impressive blend of toughness, high strength, and corrosion resistance. The alloy is composed of 21–23% chromium, 4.5–6.5% nickel, and 2.5–3.5% molybdenum, making them highly resistant to chloride-induced pitting and crevice corrosion. On the mechanical side, these valves deliver a tensile strength of around 620 MPa, a yield strength of about 450 MPa, and exceptional impact toughness and fatigue resistance. These characteristics guarantee reliable performance under high-pressure, high-temperature, and aggressive chemical conditions, extending their service life in critical applications.
