Our Super Duplex Manifold Valves are crafted from high-performance alloys that include approximately 25% chromium, nickel, molybdenum, and nitrogen. This specific blend grants them remarkable mechanical strength, with tensile strength ranging from 800 to 1000 MPa and yield strength nearly twice that of standard austenitic stainless steels. They also retain excellent toughness and ductility, even in freezing conditions. Thanks to their advanced chemical structure, these valves offer robust resistance to chloride-induced stress corrosion cracking, localized corrosion, and erosion, making them a reliable choice for critical flow control in harsh industrial settings.
