At Nasir Nickel Alloys in Manama, Bahrain, Duplex Steel 2205 Flanges are engineered to provide exceptional corrosion resistance, high mechanical strength, and long-term reliability for demanding chemical, petrochemical, marine, and industrial applications. Manufactured from a duplex stainless steel alloy with a balanced microstructure of austenite and ferrite, these flanges deliver superior resistance to pitting, crevice corrosion, and stress corrosion cracking while maintaining excellent structural integrity. Precision-engineered for leak-proof connections and consistent performance, Duplex Steel 2205 Flanges are ideal for chemical processing units, offshore platforms, marine systems, and high-pressure pipelines, offering durable and reliable solutions in aggressive environments.
Duplex Steel 2205 Flanges are primarily composed of iron, chromium, nickel, and molybdenum, with nitrogen additions to enhance corrosion resistance and mechanical strength. This composition ensures excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich and aggressive chemical environments. Mechanically, these flanges provide high tensile and yield strength, excellent toughness, and fatigue resistance under fluctuating pressures and thermal cycling. With dimensional stability and structural integrity in harsh chemical, marine, and high-pressure conditions, Duplex Steel 2205 Flanges combine superior corrosion resistance with robust mechanical performance for reliable long-term operation.
