Ashraf Nickel Alloys stands out as a reliable **manufacturer and supplier of Duplex Steel S32205 Pipe Fittings** in Riyadh, Saudi Arabia. They provide robust and corrosion-resistant piping components tailored for demanding industrial applications. Known as UNS S32205 or ASTM A815, Duplex S32205 is a nitrogen-enhanced duplex stainless steel celebrated for its remarkable strength, outstanding corrosion resistance, and impressive longevity. Ashraf Nickel Alloys specializes in precision-engineered pipe fittings, including elbows, tees, reducers, and couplings, all crafted to meet international standards. They proudly support various industries throughout Saudi Arabia and the GCC with dependable, high-performance solutions.
The composition of Duplex Steel S32205 Pipe Fittings includes around 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen. This well-balanced austenitic-ferritic microstructure grants exceptional yield strength—twice that of standard stainless steels—along with excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. These fittings are built to endure both high-pressure and corrosive environments, and their excellent weldability makes them suitable for a broad spectrum of industrial applications.
