Inconel 690 is a nickel-chromium alloy with an addition of aluminum for outstanding resistance to oxidation and other forms of high-temperature corrosion. It also has high mechanical properties at elevated temperatures. Inconel 690 is used for industrial furnaces; heat-treating equipment such as baskets, muffles and retorts; petrochemical and other process equipment; and gas-turbine components. Standard product forms are round, flats, forging stock, pipe, tube, plate, sheet, strip and wire.
