At Nasir Nickel Alloys in Manama, Bahrain, Duplex Steel S32205 Stud Bolts are produced to deliver exceptional strength, corrosion resistance, and long-term reliability in demanding environments. This duplex-grade alloy combines the benefits of austenitic and ferritic structures, offering impressive mechanical strength along with outstanding resistance to stress corrosion cracking and pitting. Designed for structural stability and durability, these stud bolts perform exceptionally well in applications exposed to chlorides, seawater, and fluctuating pressures. Duplex Steel S32205 Stud Bolts ensure secure fastening for critical systems where safety, performance, and endurance are essential.
Duplex Steel S32205 Stud Bolts are composed of chromium, nickel, molybdenum, nitrogen, and iron in a balanced duplex microstructure. This composition results in high tensile strength, excellent yield strength, and strong resistance to pitting and crevice corrosion. The presence of nitrogen enhances mechanical properties and stability, while chromium and molybdenum improve corrosion resistance in chloride-rich environments. These stud bolts maintain structural integrity under high pressure, stress, and varying temperatures. Their combination of toughness, hardness, and corrosion resistance makes them well suited for heavy-duty industrial applications.
