Ashraf Nickel Alloys stands out as a reliable **manufacturer and supplier of Duplex Steel Sheets and Plates** in Riyadh, Saudi Arabia. They specialize in delivering top-notch, corrosion-resistant steel products that meet the rigorous demands of various industrial applications. With its unique blend of austenite and ferrite, Duplex stainless steel is celebrated for its impressive mechanical strength, remarkable resistance to stress corrosion cracking, and outstanding durability in tough environments. Ashraf Nickel Alloys customizes duplex steel solutions to fit the specific needs of their clients, catering to sectors like oil & gas, petrochemicals, marine, and construction across Saudi Arabia and the broader GCC region, all while ensuring consistent quality and prompt delivery.
The Duplex Steel Sheets and Plates offered by Ashraf Nickel Alloys typically contain about 22–25% chromium, 4–7% nickel, and 3–5% molybdenum, with added nitrogen to boost strength and corrosion resistance. These materials provide a high yield strength—often twice that of regular austenitic stainless steels—while still being easy to weld and shape. Duplex steel is particularly resistant to pitting, crevice corrosion, and chloride-induced stress corrosion cracking, making it a perfect choice for challenging and corrosive settings, especially in offshore and marine applications.
