Inconel X-750 Coil Supplier, Stockist and Exporter
Table of Contents
Aurico Alloys LLP supplies inconel x-750 coil (N07750, Werkstoff 2.4669) from ready stock in Mumbai, to customers across India and in more than 40 export markets.
Coil is the most economical way to buy sheet-gauge material when parts are blanked, roll-formed or slit to strip, because it removes the cut-length premium and keeps the surface consistent along the whole run.
Inconel X-750 takes the corrosion resistance of alloy 600 and adds precipitation hardening, giving springs that hold load at temperature.

Composition limits for Inconel X-750. These are specification limits for the grade, not measured values for a lot; the mill test certificate supplied with your order states the actual analysis.
Mechanical and Physical Properties
Aged tensile strength above 1100 MPa with good relaxation resistance to 700°C and the corrosion behaviour of alloy 600.
Industry Applications
| Industry | Typical use |
|---|---|
| Aerospace | Turbine blades, rotors, bolts and springs. |
| Nuclear | Reactor springs, bolting and control-rod components. |
| Power generation | Gas-turbine hardware and high-temperature fasteners. |
| Oil and gas | Downhole springs and high-load hardware. |
| Industrial | Heat-treating fixtures and high-temperature forming tools. |
Testing and Certification
Every consignment ships with an EN 10204 3.1 mill test certificate stating heat number, chemical analysis and mechanical properties. Depending on the specification we can add positive material identification, ultrasonic and dye-penetrant testing, intergranular corrosion testing to ASTM G28 or A262, and third-party inspection release from Lloyd's Register, Bureau Veritas, SGS or TUV.
Aurico Alloys LLP operates an ISO 9001:2015 quality management system, and can certify material to NACE MR0175 / ISO 15156 for sour service where the grade permits.
