Olwan Nickel Alloys, based in Amman, Jordan, stands out as a top manufacturer and supplier of high-quality metal fasteners. They specialize in **Super Duplex Steel Screws** that are built to thrive in tough industrial settings. With a reputation for precision engineering, rigorous quality control, and compliance with international standards, the company produces screws that offer remarkable strength, resistance to corrosion, and long-lasting durability. Olwan Nickel Alloys caters to various sectors, including oil and gas, petrochemical, marine, desalination, and chemical processing. Each Super Duplex Steel Screw is meticulously designed to endure extreme pressures, chloride-rich conditions, and harsh chemicals, ensuring dependable performance and enhanced safety in critical applications.
Super Duplex Steel Screws are crafted from alloys like S32750 or S32760, which contain around 25% chromium, 6–7% nickel, 3–4% molybdenum, nitrogen, and trace elements. This well-balanced ferritic-austenitic structure grants them excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, these screws boast very high tensile and yield strength, exceptional fatigue resistance, and stability even under high temperatures and pressures. Their sturdy design ensures they remain durable and reliable for fastening, even in the most demanding industrial, offshore, and marine environments.
