Super Duplex Steel Screws are typically manufactured from grades such as UNS S32750 or S32760, containing high levels of chromium, molybdenum, and nitrogen with a balanced austenitic–ferritic structure. This composition provides exceptional resistance to corrosion, especially in chloride-rich environments. Mechanically, the material offers very high tensile and yield strength—almost twice that of conventional stainless steels—along with good toughness, fatigue resistance, and dimensional stability under heavy loads.
