Inconel 718 tubes are designed for extremely high-temperature applications where strength and durability are essential. Made from a nickel-chromium alloy, these tubes can withstand temperatures up to 1300°F without losing their strength or resistance to corrosion. They are ideal for use in applications such as gas turbine engines, rocket motors, and nuclear reactors. Our Inconel 718 tubes are manufactured using advanced techniques that ensure consistent quality and reliability. We offer a range of sizes and configurations to meet our customers' needs, and we are committed to providing exceptional customer service and support.
Alloy 718 nickel tubing is an age-hardenable nickel-chromium-iron alloy also containing significant amounts of niobium, molybdenum, titanium, and aluminum. It combines good corrosion resistance with extremely high strength. Typical applications include heat exchangers and O-rings.
Alloy 718 Tube has excellent corrosion resistance to many media. This resistance, which is similar to that of other nickel-chromium alloys, is a function of its composition. Nickel contributes to corrosion resistance in many inorganic and organic compounds, other than strongly oxidizing compounds, throughout wide ranges of acidity and alkalinity. It is also useful in combating chloride-ion stress-corrosion cracking. Chromium imparts an ability to withstand attack by oxidizing media and sulfur compounds. Molybdenum is known to contribute to resistance to pitting in many media.
