Our Nitronic 50 Tubes, also known by the UNS designation S20910, are manufactured according to ASTM A213 and ASTM A269 specifications. This alloy offers excellent corrosion resistance superior to that of types 316 and 317 stainless steels, especially in harsh environments such as saltwater exposure and acidic chemical processing. It also exhibits outstanding strength—almost double that of conventional 300 series stainless steels—making it ideal for critical applications where both corrosion resistance and strength are required.

Nitronic 60 Tubes, marked as UNS S21800, are also offered by Adinox Overseas under ASTM A213 and A269 standards. This grade is particularly renowned for its superior resistance to wear, fretting, and galling, even in dry or lubricated conditions. Nitronic 60 achieves this performance without using expensive cobalt or high levels of nickel, making it a cost-effective solution for anti-wear components. It is the material of choice for valve stems, fasteners, bushings, pump components, and marine hardware.

Nitronic 60 (UNS S21800) is highly resistant to wear and galling and is a preferred material for applications demanding superior surface stability at severe conditions. It is widely used for applications involving high mechanical stresses, such as fasteners, valve components, and pump shafts. One of the primary advantages of Nitronic 60 tubes is that they are resistant to oxidation up to 1800°F (982°C). With their high strength, coupled with corrosion resistance and low cost, they are well suited for applications involving petrochemical, food processing, and power generation.
