Chemical composition

Physical properties

Features: Alloy 625 has excellent strength at temperatures up to 816℃. 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 980℃ 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 816℃. For long term service, it is best restricted to a maximum of 593℃, because long term exposure above 593℃ will result in significant embrittlement.
