Rashid Metals is a reputable manufacturer and supplier of top-notch Duplex Steel S31803 Bars and Rods based in Muscat, Oman. We pride ourselves on our commitment to quality assurance, cutting-edge processing techniques, and adherence to international standards. Serving various demanding industries throughout the Middle East and beyond, our Duplex Steel S31803 bars and rods are crafted to provide outstanding strength, impressive corrosion resistance, and precise dimensional accuracy. Built to withstand harsh conditions and high-pressure environments, these products ensure long-lasting reliability and performance in critical structural and engineering applications.
Duplex Steel S31803 is a unique blend of chromium, nickel, and molybdenum stainless steel, featuring a well-balanced austenitic and ferritic microstructure. This combination grants it remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. In terms of mechanical properties, S31803 bars and rods boast high tensile and yield strength—almost double that of standard austenitic stainless steels—while also offering good ductility and impact toughness. They retain their strength and structural integrity even under high pressure and at moderate to elevated temperatures.
