ASTM B444 UNS N06625 / Inconel 625 Gr.2 Nickel Alloy Seamless U Tube for Heat Exchanger
Grade Inconel 625 / UNS N06625 has excellent strength at temperatures up to 816℃. At higher temperatures, its strength is generally lower than that of other solid solution strengthened alloys. Alloy625 has good oxidation resistance at temperature up to 980℃ and shows good resistance to aqueous corrosion, but is relatively moderate compared to other more capable corrosion resistant alloys.
