Quick Answer: Inconel 718 bar, also known as UNS N07718 or Alloy 718 bar, is a precipitation-hardenable nickel-chromium alloy bar selected for high strength, creep resistance and corrosion resistance up to elevated temperatures. J&A Alloy can quote standard and custom Inconel 718 bar sizes with MTC, PMI, UT, cutting and export packing options.

This supplier page is designed for buyers who already know they need Inconel 718 in bar or rod form and want to confirm available specifications, size information, heat treatment condition, inspection requirements and RFQ details.

Common Applications for Inconel 718 Bar

ApplicationWhy Inconel 718 Bar Is UsedProcurement Notes
Aerospace fasteners and structural hardwareHigh strength after aging, good fatigue resistance and strong specification control.Confirm AMS specification, heat treatment and traceability.
Turbine and hot-section componentsStrength retention, creep resistance and oxidation resistance at elevated temperature.Confirm working temperature, stress level and inspection.
Oil & gas and sour service partsHigh strength combined with nickel alloy corrosion resistance.Confirm NACE/project requirements, hardness and condition.
Shafts, bolts, rings and machined partsUseful where high strength and dimensional stability are required.Send drawing, final dimensions and machining allowance.
Cryogenic and pressure equipment componentsGood mechanical properties across demanding temperature ranges.Confirm applicable ASME/ASTM requirements and tests.

Heat Treatment and Material Condition

Inconel 718 bar properties depend strongly on heat treatment. Buyers should specify whether the bar is required in solution annealed, aged, precipitation-hardened, as-forged or custom condition. If your drawing only gives mechanical properties, send the target tensile strength, yield strength, elongation, hardness and test standard so our team can quote a practical condition.

ConditionTypical UseWhat to Confirm
Solution annealedFurther forming, machining or project-specific agingAnnealing standard, grain size or later heat treatment plan.
Age hardened / precipitation hardenedHigh-strength finished components, fasteners and shaftsAMS/ASTM condition, tensile properties, hardness and test report.
