Product Description
Alloy 625 (UNS N06625/W.Nr. 2.4856) is used for its high strength, excellent fabricability (including joining), and outstanding corrosion resistance. Service temperatures range from cryogenic to 1800°F (982°C). Strength of alloy 625 is derived from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix; thus precipitationhardening treatments are not required. This combination of elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization.
FEATURES
Alloy 625 has excellent strength at temperatures up to 816ºC. At higher temperatures, its strength is generally lower than that of other solid solution strengthened alloys. Alloy 625 has good oxidation resistance at temperatures up to 980ºC and shows good resistance to aqueous corrosion, but is relatively moderate compared to other more capable corrosion resistant alloys.
APPLICATIONS
Chemical process industry and sea water application. Alloy 625 is used in short term applications at temperatures up to 816ºC. For long term service, it is best restricted to a maximum of 593C, because long term exposure above 593ºC will result in significant embrittlement.
