Olwan Nickel Alloys, located in Amman, Jordan, stands out as a top manufacturer and supplier of high-performance industrial materials, particularly premium Duplex Steel Coils. With a reputation for precision engineering and cutting-edge production technology, the company is committed to upholding international quality standards. Their coils are crafted for exceptional durability and corrosion resistance, catering to demanding sectors like oil and gas, petrochemical, marine, and construction. Olwan Nickel Alloys guarantees consistent product quality, ensuring that their Duplex Steel Coils deliver impressive mechanical strength and long-lasting reliability, making them perfect for tough environments, high stress, and corrosive conditions.
Duplex Steel Coils are made from a carefully balanced blend of austenitic and ferritic stainless steels, typically featuring 22–25% chromium, 5–6% nickel, 3–5% molybdenum, and controlled nitrogen levels. This unique composition grants them outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, particularly in chloride-rich settings. On the mechanical side, Duplex Steel Coils boast high tensile and yield strength, excellent toughness, and dependable performance even under fluctuating temperatures and high pressure. Their dual-phase microstructure not only enhances durability but also improves ductility, making them ideal for heavy-duty industrial applications where strength and corrosion resistance are crucial.
