At Nasir Nickel Alloys in Manama, Bahrain, Duplex Steel 2205 Fasteners are engineered to provide superior strength, corrosion resistance, and reliability in demanding industrial applications. Made from a balanced duplex stainless steel alloy, these fasteners combine the toughness of ferritic steel with the ductility of austenitic steel, offering high tensile strength and excellent resistance to stress-corrosion cracking. Designed for critical fastening applications, Duplex Steel 2205 Fasteners maintain structural integrity and dimensional stability under high-pressure, high-temperature, and chemically aggressive conditions. Their durability makes them ideal for chemical, petrochemical, offshore, marine, and power generation industries.
Duplex Steel 2205 Fasteners are composed of approximately 22% chromium, 5–6% nickel, and 3% molybdenum, with a dual-phase structure of ferrite and austenite. This composition provides high tensile and yield strength while retaining excellent toughness and ductility. The alloy exhibits outstanding resistance to pitting, crevice corrosion, and chloride-induced stress-corrosion cracking. Duplex Steel 2205 Fasteners maintain dimensional stability under thermal cycling and mechanical loading, ensuring secure and reliable fastening. Their combination of mechanical strength, corrosion resistance, and durability makes them ideal for demanding industrial and marine environments.
