Inconel should be used under hot corrosive conditions requiring resistance to intergranular attack and stress corrosion. Inconel is most commonly used under oxidizing conditions to handle hot corrosives or corrosive vapors where stainless steel might be subject to intergranular attack or stress corrosion cracking. In recent years, Inconel has found large scale applications in handling hot boiler feedwater in nuclear plants because of a greater margin of safety over stainless steels.

Common Inconel materials offered:

• Inconel 600 — A494 CY40
• Inconel 625 — A494 CW6MC
• Inconel 825 — A494 CU5MCUC
