Inconel 718 specifications

Inconel 718 (UNS N07718, W.Nr 2.4668, NiCr19NbMo): round bar and forgings ASTM B637; plate, sheet and strip ASTM B670 / ASME SB670. Aerospace drawings often cite AMS 5662 or AMS 5663 for bar and AMS 5596 for sheet and plate; tell us which one applies.

Stocked forms: round bar, plate and sheet, from Mumbai stock. Pipe, tube and flanges: sizes confirmed per enquiry, from Mumbai stock.

Condition matters: 718 is bought solution annealed for machining and then aged by the customer, or supplied already solution treated and aged. State the condition on your order; the MTC records it.

Comparing grades: Inconel 625 is chosen for corrosion and weldable plate work, Inconel X-750 for springs and older high-temperature designs, and 718 when high strength at temperature with good weldability is the priority.

Typical chemistry: Ni 50–55%, Cr 17–21%, Nb+Ta 4.75–5.5%, Mo 2.8–3.3%, Ti 0.65–1.15%, Al 0.2–0.8%, iron balance. Density about 8.19 g/cm³.

Minimum properties, ASTM B637 solution treated and aged bar: tensile 1275 MPa, yield 1034 MPa, elongation 12%. Solution-annealed bar is much softer, which is why shops rough-machine before ageing.

Machining note: 718 work-hardens quickly. Shops usually rough in the annealed condition with rigid set-ups and sharp carbide, then age, then finish-machine to size.

718 bar, plate and sheet: what Chennai shops buy

Machine shops mostly buy 718 round bar cut to blank length for shafts, fasteners, rings and fittings. Fabricators buy plate and sheet cut to size for brackets, seal housings and formed parts. Each blank or cut piece carries the heat number, so the traceability chain your quality plan asks for is not broken at the saw.
