At Adinox Overseas, we specialize in offering top-grade Nitronic 50 Plates (UNS S20910) and Nitronic 60 Plates (UNS S21800) manufactured under the global specification ASTM A240. These austenitic stainless steels are engineered for demanding environments requiring superior strength, oxidation resistance, and outstanding corrosion resistance, especially in marine and chemical processing industries. Our Nitronic plates are highly regarded across multiple sectors including aerospace, oil and gas, power generation, and food processing due to their extended service life and low maintenance properties.
Nitronic 50 is known for its excellent combination of mechanical strength and corrosion resistance. It offers almost twice the yield strength of 316/316L and maintains good ductility and toughness even in cryogenic environments. The UNS S20910 alloy also exhibits excellent resistance to pitting and crevice corrosion, making it ideal for marine environments and high-chloride applications. This stainless steel is non-magnetic in both the annealed and cold worked conditions, making it a prime choice for critical industrial applications.
Nitronic 60, or UNS S21800, is specially developed for superior wear and galling resistance. It is widely used in applications involving metal-to-metal contact, such as valves, shafts, fasteners, and pump components. Unlike conventional stainless steels, Nitronic 60 maintains excellent high-temperature strength and oxidation resistance up to 1800°F. Its unique silicon and manganese-enhanced composition help prevent adhesive wear, making it a cost-effective alternative to cobalt and nickel alloys in wear-intensive applications.
Both Nitronic 50 and Nitronic 60 Plates comply with ASTM A240 standards, ensuring global acceptance and trust in quality. These plates can be hot rolled or cold rolled, depending on the customer's requirements, and are available in a variety of thicknesses and sizes. Our products undergo strict quality checks and meet all international standards for dimensional accuracy, finish, and mechanical performance.
