Alloy 556 Material Properties

Alloy 556 (UNS R30556) is a high-performance nickel alloy. It offers good high-temperature strength, oxidation resistance, and carburization resistance. Alloy 556 is suitable for boiler systems and high-temperature heat exchange applications.The alloy maintains stable microstructure during long-term high-temperature service and shows strong resistance to sulfide environments and complex atmospheres, making it suitable for continuous operating conditions. Our alloy 556 seamless pipes are heat treated strictly in accordance with relevant standards to ensure reliable performance in high-temperature applications.
