Adinox Overseas is a trusted manufacturer and exporter of premium quality Nitronic 50 and Nitronic 60 Sheets, engineered to deliver superior mechanical properties and corrosion resistance for the most demanding applications. These advanced stainless steel sheets are widely recognized for their unique combination of strength, wear resistance, and pitting corrosion resistance, making them ideal for critical components used in marine, aerospace, chemical processing, and valve industries.
Nitronic 50 Sheets, also known by their UNS number S20910, are an austenitic stainless steel alloy that offers nearly double the yield strength of 316 stainless steel while maintaining excellent corrosion resistance. These sheets conform to ASTM A240 standards and are known for their high resistance to chloride-induced stress corrosion cracking and pitting, especially in saltwater environments. The alloy is non-magnetic even after severe cold working and retains outstanding mechanical strength even at sub-zero temperatures, making it highly suitable for pump shafts, fasteners, and marine hardware.
Nitronic 60 Sheets, identified by UNS number S21800, are designed for wear and galling resistance. These sheets also meet ASTM A240 specifications and are commonly used in applications requiring enhanced resistance to metal-on-metal wear such as in valve stems, seatings, pins, and bushings. The manganese and silicon additions in Nitronic 60 provide superior resistance to adhesive wear compared to standard stainless steels like 304 and 316, offering a reliable solution in applications involving friction or metal-to-metal contact.
Adinox Overseas delivers Nitronic 50 and 60 Sheets in a variety of dimensions, finishes, and customized sizes to meet specific client requirements across industries. All sheets are manufactured under stringent quality control, backed by test certificates, and available for global dispatch.
