Features:
Inconel 625 has excellent strength at temperatures up to 816¡æ. Its power is generally lower at higher temperatures than other solid solution-strengthened alloys. Inconel 625 has good oxidation resistance at temperatures up to 980¡æ 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. Inconel 625 is used in short-term applications at temperatures up to 816¡æ. For long-term service, it is best restricted to a maximum of 593¡æ, because long-term exposure above 593¡æ will result in significant embrittlement.
