Inconel 718 Tube Extrusion And Drawing Techniques For Improved
Mechanical Properties
Our cost-effective Inconel 718 tube manufacturing process allows us
to offer reduced lead times, making it easier than ever to get the
products you need when you need them. Made from a nickel-chromium
alloy, these tubes offer excellent resistance to both corrosion and
high-temperature environments. Our manufacturing process is
designed to be efficient and effective, allowing us to produce
high-quality tubes at a lower cost. We offer a range of sizes and
configurations to meet the needs of our customers, 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, 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.
