Alloy 690 Pipe Inconel 690 Pipe (UNS N06690) is a high-chromium, nickel-based alloy with excellent resistance to corrosion by a variety of aqueous media and high-temperature atmospheres. It also has high strength, good metallurgical stability and excellent processing characteristics.

Alloy 690 Pipe Inconel 690 Pipe Application

The alloy’s ability to resist sulfur-containing atmospheres makes it used as a coal gasification device, a burner and furnace tube for sulfuric acid treatment, a petrochemical furnace, a heat exchanger tube, an incinerator, and a glass curing equipment for disposal of radioactive waste. The alloy shows excellent low corrosion rate and stress corrosion resistance in various types of high-temperature water, so it is widely used in steam generator heat transfer tubes, separators, tube sheets and nuclear power components.
