Alloy 600 Inconel is a nickel chromium alloy with good oxidation resistance at elevated temperatures, resistance to stress corrosion cracking, caustic corrosion and ultra high purity water corrosion. Typical applications include furnace components, chemical and food processing, nuclear engineering and sparking electrodes.

Alloy x-750 Inconel is similar to alloy 600 but is hardenable due to the addition of Ti and Al. In addition to good corrosion and oxidation resistance it also has high tensile strength and creep properties to around 700° C. Its resistance to relaxation makes it suitable for high temperature springs and it is also used in rocket engines, nuclear reactors, aircraft, tooling and pressure vessels.
