At Nasir Nickel Alloys in Manama, Bahrain, Duplex Steel 2205 Nuts are engineered to deliver exceptional strength, corrosion resistance, and reliability in high-demand industrial environments. This dual-phase stainless steel combines the toughness of ferritic steel with the ductility of austenitic steel, offering superior tensile strength and excellent resistance to stress-corrosion cracking. Designed for critical fastening applications, Duplex Steel 2205 Nuts maintain structural integrity and dimensional stability under high-pressure, high-temperature, and chemically aggressive conditions. Their durability makes them an ideal choice for chemical, petrochemical, offshore, marine, and power generation industries requiring secure and long-lasting connections.
Duplex Steel 2205 Nuts are composed of approximately 22% chromium, 5–6% nickel, 3% molybdenum, and a balanced mixture of austenite and ferrite. This composition ensures high tensile and yield strength while maintaining toughness and ductility. The alloy demonstrates excellent resistance to pitting, crevice corrosion, and chloride-induced stress-corrosion cracking. Duplex Steel 2205 Nuts retain dimensional stability under thermal cycling and mechanical stress, ensuring secure fastening in demanding applications. Their combination of mechanical strength, toughness, and corrosion resistance makes them reliable for critical, high-performance industrial environments.
