Inconel X-750
Aurico Alloys LLP supplies Inconel X-750 (UNS N07750, W.Nr. 2.4669) as sheet, plate, coil and round bar, with EN 10204 3.1 mill test certificates and export packing from Mumbai, India.
Key Properties
- Titanium 2.25-2.75%, aluminium 0.40-1.00% and niobium with tantalum 0.70-1.20% on nickel 70% minimum, chromium 14-17% and iron 5-9%.
- An age-hardened grade. Special Metals publishes how much it contracts in the precipitation treatment from the annealed, hot-rolled and 20% cold-rolled conditions: the figures are in the table below.
- Essentially non-magnetic at room temperature. Its Curie temperature, also below, is well under zero both hot-rolled and triple-heat-treated, the two conditions Special Metals publishes it for.
