High-Quality Inconel 718 Tube Production With Strict Quality Control Measures
Our innovative tube forming techniques for Inconel 718 alloy allow us to create products that are customized to the unique needs of each customer. Made from a nickel-chromium alloy, these tubes offer excellent resistance to both corrosion and high-temperature environments.
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, other than strongly oxidizing, compounds throughout wide ranges of acidity and alkalinity. It also is 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.
