Inconel Coil Supplier, Stockist and Exporter

Aurico Alloys LLP supplies inconel coil 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 covers nickel-chromium superalloys that retain strength and resist oxidation far above the limit of stainless steel. In-house slitting, cut-to-length, levelling and edge conditioning let us ship coil already sized for your press or roll former.

Chemical Composition

Inconel 600 carries 72% Ni with 14-17% Cr and 6-10% Fe; Inconel 625 adds 8-10% Mo and 3.15-4.15% Nb for solid-solution strengthening; Inconel 718 is age-hardened through 4.75-5.5% Nb plus titanium and aluminium.

Mechanical and Physical Properties

Room-temperature tensile strength ranges from about 550 MPa (600, annealed) to 1275 MPa (718, aged). Grade 625 resists oxidation to 1050°C, and 718 holds useful strength to roughly 700°C.

Industry Applications

How coil and strip is used

Coil and strip are continuous cold-rolled flat product, bought to be worked rather than installed as they arrive. The common routes are stamping and deep drawing of gaskets, bellows, diaphragms and seals; forming of springs and spring washers; slitting to narrow strip for electrical contacts, battery tabs and current collectors; shim and vessel-lining stock; and as the feedstock from which welded tube and pipe are made. Thickness tolerance and temper matter more here than they do in any other form, because the material has to survive the press.

Where inconel coil is specified
IndustryTypical use
AerospaceTurbine casings, combustion liners, exhaust ducting and fasteners.
Chemical processingAcid-service reactors, bellows and evaporator tubing.
Oil and gasSour-service completion equipment, subsea hardware and flare tips.
Power generationSteam-generator tubing, gas-turbine hardware and nuclear components.
MarineSeawater systems and splash-zone hardware.

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 grade and specification we can supply positive material identification (PMI), ultrasonic and dye-penetrant testing, intergranular corrosion testing to ASTM A262 or G28, and third-party inspection release notes from Lloyd's Register, Bureau Veritas, SGS or TUV.

Aurico Alloys LLP operates an ISO 9001:2015 quality management system. Material for sour service can be supplied certified to NACE MR0175 / ISO 15156 where the grade permits.
