Ashraf Nickel Alloys stands out as a reliable manufacturer and supplier of Super Duplex Steel Bars in Riyadh, Saudi Arabia. We pride ourselves on delivering top-notch bars that are built for strength, durability, and resistance to corrosion. Crafted from high-quality Super Duplex stainless steel, these bars feature a well-balanced austenitic-ferritic structure, providing outstanding protection against pitting, crevice corrosion, and stress corrosion cracking, even in harsh environments. Available in various shapes like round, square, hex, and flat bars, they comply with global ASTM, ASME, and UNS standards. Our precision-engineered Super Duplex Steel Bars are extensively utilized in marine, offshore, chemical, and oil & gas sectors, ensuring dependable performance under extreme conditions.
Super Duplex Steel Bars are generally composed of around 25% chromium, 7% nickel, 3–4% molybdenum, and nitrogen, which gives them a high PREN (>40) for excellent corrosion resistance. These bars boast a tensile strength ranging from 750 to 1,000 MPa and a yield strength of about 550 MPa, along with impressive impact toughness, even in freezing temperatures. Their unique dual-phase microstructure enhances fatigue resistance, dimensional stability, and weldability. This special composition makes them perfect for chloride-rich environments and demanding industrial applications, ensuring minimal upkeep, long-lasting strength, and reliability.
