Ashraf Nickel Alloys stands out as a reliable manufacturer and supplier of Super Duplex Steel Slitting Coils in Riyadh, Saudi Arabia. We pride ourselves on delivering top-notch coil solutions that industries depend on for outstanding corrosion resistance and strength. Our coils are crafted according to ASTM, ASME, and UNS specifications, featuring a well-balanced austenitic-ferritic microstructure that guarantees exceptional toughness and resistance to pitting, crevice corrosion, and stress corrosion cracking. Perfectly designed for precision slitting and tight dimensional tolerances, these coils are a great fit for sectors like oil and gas, marine, desalination, chemical, and power generation. With their high strength, durability, and various surface finish options, our slitting coils ensure long-lasting reliability and performance.
Super Duplex Steel Slitting Coils are composed of 24–26% chromium, 6–8% nickel, 3–4% molybdenum, along with additions of tungsten, nitrogen, and manganese, achieving a PREN >40 for remarkable corrosion resistance. They boast a tensile strength exceeding 800 MPa, a yield strength of 550 MPa, and impressive toughness at both high and low temperatures. The dual-phase structure enhances fatigue strength and resistance to chloride-induced cracking. Manufactured to meet ASTM A240, ASTM A276, and ASME SA specifications, these coils are dimensionally accurate, offering excellent formability, machinability, and weldability, making them perfect for industries that require durable, high-performance materials.
