At Nasir Nickel Alloys in Manama, Bahrain, Duplex Steel S32205 Pipe Fittings are engineered to provide exceptional strength, corrosion resistance, and long-term durability in demanding industrial applications. Manufactured from high-quality duplex stainless steel, these fittings feature a balanced austenitic-ferritic microstructure that ensures superior mechanical properties and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Each fitting is precision-crafted for secure, leak-proof connections and reliable performance. Designed for chemical, petrochemical, marine, and industrial systems, Duplex Steel S32205 Pipe Fittings deliver dependable solutions for high-pressure and aggressive environments, ensuring safe, efficient, and long-lasting operation.
Duplex Steel S32205 Pipe Fittings are composed of approximately 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, offering excellent resistance to chloride-induced corrosion, pitting, and stress corrosion cracking. The duplex microstructure provides high tensile and yield strength, superior toughness, and fatigue resistance under fluctuating pressures and elevated temperatures. These fittings maintain dimensional stability under thermal cycling and mechanical stress. The combination of corrosion resistance and mechanical strength ensures reliable long-term performance, making Duplex Steel S32205 Pipe Fittings ideal for harsh chemical, marine, and high-pressure industrial applications.
