Aisha Nickel Alloys is a reputable manufacturer and supplier of Duplex Steel S32205 Flanges, proudly based in Muscat, Oman. They cater to a wide range of industrial needs throughout the Middle East and beyond. Renowned for their precision engineering and rigorous quality control, the company provides flanges that adhere to international standards like ASTM and ASME. The Duplex Steel S32205 Flanges from Aisha Nickel Alloys are known for their impressive strength and outstanding resistance to corrosion and stress cracking. With state-of-the-art manufacturing facilities, prompt delivery, and a strong focus on customer satisfaction, they deliver reliable, durable, and cost-effective flange solutions for even the most challenging operating conditions.
These flanges are crafted from a well-balanced microstructure of austenite and ferrite, typically featuring around 22% chromium, 5–6% nickel, 3% molybdenum, and low carbon content. This unique composition grants them exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. On the mechanical side, S32205 flanges boast high tensile and yield strength—almost double that of standard austenitic stainless steels. They also demonstrate good toughness, fatigue strength, and weldability, making them ideal for high-pressure and high-temperature applications.
