Ashraf Nickel Alloys stands out as a top manufacturer and supplier of Super Duplex Steel Sheets and Plates in Riyadh, Saudi Arabia. We pride ourselves on delivering high-quality products that meet the demands of industries needing exceptional strength, corrosion resistance, and reliability. Our sheets and plates are crafted to comply with ASTM, ASME, DIN, and ISO standards, making them perfect for use in harsh, chloride-rich environments. With a unique dual-phase microstructure, Super Duplex stainless steel provides double the strength of standard austenitic grades while offering remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. Available in various sizes, thicknesses, and finishes, they find extensive applications in marine, chemical, oil & gas, and desalination sectors.
Super Duplex Steel is composed of 25% chromium, 7% nickel, 4% molybdenum, along with trace elements like nitrogen, manganese, and silicon, all contributing to its superior corrosion resistance. It boasts a yield strength of about 550 MPa and a tensile strength of 800 MPa, making it perfect for heavy-duty applications. With a PREN (Pitting Resistance Equivalent Number) greater than 40, it performs exceptionally well in seawater and acidic environments. Super Duplex sheets and plates are known for their high toughness, fatigue strength, low thermal expansion, and excellent weldability, making them ideal for structural, industrial, and engineering applications that require long-lasting durability and minimal upkeep.
