Inconel 718 Bars

Inconel 718 Bars are high-strength nickel-chromium alloys designed to handle extreme heat and stress. It remains strong across a broad temperature range and provides exceptional resistance to oxidation and corrosion. Metracore Alloys is a leading manufacturer and supplier of 718 Inconel round bars with strict quality control to meet global standards. The alloy contains nickel (50–55%), chromium (17–21%), iron (balance), molybdenum (2.8–3.3%), niobium with tantalum (4.75–5.5%), along with smaller amounts of titanium, aluminum, and cobalt. These bars have a proof stress of 1034 MPa, tensile strength of 1275 MPa, hardness of 331 HB, and good elongation and reduction of area values.

Our Inconel 718 bars are offered in a wide range of sizes from 33mm x 30mm to 295mm x 1066mm. They are available in finishes such as bright, polished, rough turned, ground, centreless ground, and black. These bars show strong fatigue resistance, excellent creep strength, and stable performance under both low and high temperatures. This makes them reliable for industries where safety and durability are critical.

These bars are used in jet engines and gas turbines; they form discs, shafts and blades that face high heat and pressure. In the oil and gas sector, they are made into wellhead completion equipment and mandrels that resist corrosion in deep wells. The aerospace industry uses them for fasteners that hold components securely under vibration and stress. For instrumentation parts, their stability ensures accurate performance even in harsh environments. In every case, Inconel 718 bars provide long service life and reduce the risk of part failure.
