At Nasir Nickel Alloys in Manama, Bahrain, Duplex Steel 2205 Stud Bolts are engineered to deliver exceptional performance in environments where high strength, corrosion resistance, and durability are essential. As a leading duplex-grade alloy, 2205 combines the advantages of both austenitic and ferritic structures, offering superior mechanical properties and excellent resistance to stress corrosion cracking. These stud bolts remain stable under fluctuating temperatures and pressures, making them ideal for demanding applications. Duplex Steel 2205 Stud Bolts are designed to provide long-lasting, secure fastening solutions in industries where reliability and safety are paramount.
Duplex Steel 2205 Stud Bolts are composed of chromium, nickel, molybdenum, nitrogen, and iron, forming a balanced duplex microstructure that enhances strength and corrosion resistance. The alloy offers high tensile and yield strength, along with excellent toughness and hardness. Chromium and molybdenum improve resistance to pitting, crevice corrosion, and chloride-induced attack, while nitrogen increases structural stability and mechanical performance. These stud bolts maintain integrity under high pressure, elevated temperatures, and dynamic loading, providing dependable fastening in aggressive and demanding industrial conditions.
