ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering AMS 5532J Multimet N155 sheet at factory-direct prices with full material traceability and fast global delivery. AMS 5532J specification covers a corrosion- and heat-resistant iron alloy (Multimet N155 / UNS R30155) in the form of sheet, strip, and plate. Multimet N155 is a nickel-chromium-cobalt-iron alloy with additions of molybdenum and tungsten. Its high-temperature properties are inherent in the as-supplied condition (solution treated at 1177°C / 2150°F) and are not dependent on age-hardening. The alloy is typically used in parts requiring high strength up to 732°C (1350°F) and oxidation resistance up to 982°C (1800°F).
