Olwan Nickel Alloys, based in Amman, Jordan, stands out as a top manufacturer and supplier of high-performance stainless steel products, with a special focus on Duplex Steel bolts. Known for their precision, durability, and adherence to international standards, Olwan Nickel Alloys crafts bolts designed for tough industrial, marine, and offshore settings. These Duplex Steel bolts boast remarkable corrosion resistance, impressive mechanical strength, and a strong defense against stress corrosion cracking, ensuring safe and dependable fastening even in the harshest conditions. Catering to sectors like chemical processing, oil and gas, power generation, and marine, the company employs cutting-edge manufacturing methods and strict quality control to produce bolts that promise long-lasting performance and structural integrity.
Duplex Steel bolts are made up of about 22% chromium, 5–6% nickel, and 3% molybdenum, featuring a balanced ferrite-austenite microstructure. This unique blend offers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. On the mechanical side, these bolts showcase high tensile and yield strength, exceptional toughness, and solid fatigue resistance. The duplex microstructure guarantees dimensional stability and durability, even under heavy loads and thermal stress. By merging corrosion resistance with mechanical strength, Duplex Steel bolts are perfect for critical fastening tasks in chemical, marine, offshore, and industrial settings that demand long-term reliability.
