Haynes Alloy Coil Supplier, Stockist and Exporter

Aurico Alloys LLP supplies haynes alloy 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.

Haynes Alloy covers nickel- and cobalt-base high-temperature alloys for oxidising, carburising and thermal-fatigue service. In-house slitting, cut-to-length, levelling and edge conditioning let us ship coil already sized for your press or roll former.

Chemical Composition

Haynes 230 is a Ni-22Cr-14W-2Mo alloy with lanthanum for oxide adherence. The cobalt-base grades 25 and 188 carry roughly 20% chromium with 15% tungsten and 20-22% nickel over a cobalt balance.

Mechanical and Physical Properties

Haynes 230 holds about 860 MPa tensile at room temperature and resists oxidation to 1150°C. Grade 282 combines gamma-prime strength with weldability and creep resistance to roughly 900°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.

Power generationGas-turbine hot-gas-path components and hot ducting.
Chemical processingCatalyst grid supports and high-temperature reactor internals.
Heat treatmentMuffles, retorts, fixtures and radiant tubes.
Industrial heatingBurner nozzles and furnace 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.
