Inconel 690 Tubing has a chemical composition of nickel, chromium, and iron that differs slightly based on the specific grade. More specifically, it contains at least 65 percent nickel and 20 to 25 percent chromium with smaller amounts of carbon, manganese, aluminum, silicon, phosphorus, sulfur, and other elements. This composition makes Inconel 690 Tubing resistant to environmental conditions such as high pressure and temperature extremes. It is also highly resistant to corrosion in reduced and oxidizing atmospheres, giving it utility in critical applications related to power generation or aerospace components.

690 Inconel Tubing has been a standard material used in industries for some time due to its many advantageous properties. This nickel-chromium alloy offers excellent oxidation and corrosion resistance, making it ideal for resistive applications handling highly corrosive chemicals or operating in temperatures beyond the range of carbon steels. In addition, Inconel tubing also offers good chemical and mechanical strength, good formability and weldability, enhanced creep strength, and higher stress rupture properties at all temperatures. As a result, it has become essential to chemical processing, flue gas desulfurization systems in power plants, and other heat-treating machinery from aerospace to automotive.
