Adinox Overseas is a leading manufacturer and global supplier of high-performance Alloy 20 Wires, crafted to meet the most demanding industrial applications. Designated under the UNS N08020 and developed in accordance with ASTM B473 standards, these wires are also commonly referred to by their universal standard name, Carpenter 20. Alloy 20, a nickel-iron-chromium-based austenitic alloy with additions of copper and molybdenum, is specifically engineered to provide superior resistance against sulfuric acid and chloride-induced pitting and crevice corrosion.
Alloy 20 wire is a popular choice across a variety of sectors including chemical processing, pharmaceutical production, food and beverage industries, power generation, and marine environments. The alloy’s unique chemical composition allows it to outperform conventional stainless steels like 316L in aggressive environments, especially in conditions involving hot sulfuric acid. This makes UNS N08020 Wire a reliable and economical option for critical operational setups.
At Adinox Overseas, our Alloy 20 Wires are manufactured using advanced cold drawing and annealing processes, ensuring dimensional accuracy, smooth finish, and high tensile strength. These wires are available in various forms such as spools, coils, and straight lengths, and can be tailored to specific diameters and tolerances to suit client requirements. Our strict adherence to international quality control protocols and certifications ensures that every batch of Alloy 20 Wires meets the highest global standards, including ISO, NACE, and ASTM specifications.
Our wires are exported worldwide and are well-regarded by industries for their consistency and conformity to international norms. Every wire undergoes rigorous testing procedures such as mechanical testing, hydro testing, PMI testing, and ultrasonic inspection to ensure defect-free delivery. For premium grade Alloy 20 Wires UNS N08020 that meet the critical demands of corrosion resistance and mechanical performance, Adinox Overseas is your trusted partner.
