At Nasir Nickel Alloys in Manama, Bahrain, Duplex Steel 2205 Tubing is engineered to deliver superior strength, corrosion resistance, and durability for demanding industrial environments. Featuring a balanced austenitic-ferritic microstructure, this tubing resists pitting, crevice corrosion, and stress-corrosion cracking in chloride-rich and chemically aggressive conditions. Manufactured with precision for dimensional stability and consistent mechanical properties, Duplex Steel 2205 Tubing ensures reliable, leak-tight performance under high-pressure and thermal cycling conditions. Ideal for chemical processing, petrochemical, oil and gas, power generation, and marine applications, it provides robust and high-performance solutions for critical piping and structural systems.
Duplex Steel 2205 Tubing is composed primarily of chromium, nickel, molybdenum, and nitrogen, creating a balanced austenitic-ferritic microstructure. This composition provides high tensile and yield strength, excellent toughness, and superior resistance to pitting, crevice corrosion, and stress-corrosion cracking. The tubing maintains dimensional stability and mechanical integrity under thermal cycling, high-pressure, and mechanically demanding conditions. Combining corrosion resistance, high strength, and durability, Duplex Steel 2205 Tubing ensures long-lasting and reliable performance in chemical, petrochemical, marine, offshore, and power generation applications where conventional stainless steels may fail.
