ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering Alloy 625 at factory-direct prices with full material traceability and fast global delivery.
Alloy 625 (UNS N06625 / W.Nr. 2.4856) is a nickel-chromium-molybdenum alloy with an addition of niobium. The combination of molybdenum and niobium stiffens the alloy matrix, providing high strength without the need for a strengthening heat treatment.
This solid-solution strengthened alloy resists a wide range of corrosive environments and offers excellent resistance to pitting and crevice corrosion. It is widely used in chemical processing, aerospace, marine engineering, oil & gas, pollution control equipment, and nuclear reactors.
Welding: Excellent weldability using GTAW (TIG), GMAW (MIG), and resistance welding; matching filler metal (ERNiCrMo-3) recommended
