Inconel 693/UNS N06693

Inconel 693, also known as Alloy 693 and UNS N06693, is a nickel-chromium alloy specifically developed for superior resistance to oxidation and carburization at high temperatures. With the addition of aluminum, the alloy forms a tightly adherent oxide film, which provides excellent protection in oxidizing and sulfidizing environments. This makes it an advanced material for applications where prolonged exposure to extreme heat is required.

Inconel 693 is widely used in industries such as petrochemical processing, thermal power generation, and heat treatment equipment. Typical applications include furnace components, burner nozzles, petrochemical heaters, and other parts subjected to aggressive atmospheres. It is available in multiple product forms, including Inconel 693 plates, sheets, tubes, bars, and fittings, offering versatile solutions for high-temperature corrosion resistance.
