FAQs
Solution annealing at 1150°C (2102°F) followed by aging at 840°C (1544°F) achieves optimal mechanical properties.
Yes, our Inconel 722 products meet NACE MR0175/ISO 15156 standards for hydrogen sulfide (Hâ‚‚S) environments.
Absolutely. Its high chromium and molybdenum content ensures resistance to sulfidation and carburization.
Inconel 722 offers higher temperature capability (980°C vs. 700°C) and superior creep resistance due to cobalt and titanium additions.
