When a combined-cycle power station upgraded its HRSG ducting and furnace internals to higher firing temperatures for improved efficiency, conventional iron–nickel alloys began scaling, cracking, and warping within 18 months, forcing repeated shutdowns. The turnaround came with Haynes® 230 Sheets (UNS N06230), a nickel–chromium–tungsten–molybdenum alloy designed for high-temperature strength and superior resistance to oxidation, nitridation, and carburization up to about 1150°C, which extended component life well beyond 60,000 hours and drastically reduced unscheduled outages.

For procurement heads, engineers, fabricators, OEM manufacturers, and hardware or industrial supply stores serving chemical, oil & gas, marine, pharma, and power generation, Haynes 230 offers a distinct performance advantage over standard stainless and conventional Ni–Cr alloys. It combines excellent creep and rupture strength, thermal stability, and environmental resistance, making it ideal for gas turbine combustor liners, transition ducts, furnace fixtures, catalyst supports, and boiler components where failure can mean catastrophic downtime.
Aurico Alloys LLP acts as a reliable Haynes® 230 Sheets supplier, stockist, and exporter in India to abroad, providing affordable, best quality, authentic material for critical projects in chemical, oil & gas, marine, pharma, and power industries, as well as for hardware and industrial supply stores. Customers benefit from ready stock, cut-to-size service, and competitive UNS N06230 sheet price per kg, backed by full mill test certificates and international standard compliance.
For designs that also incorporate Nimonic 81 in combustion chambers or high-temperature fasteners, Aurico supports a consolidated procurement strategy similar to a Nimonic 81 sheets supplier, ensuring consistent quality and traceability across different alloy families including Haynes 230 for static hot-section liners and Nimonic grades for rotating or highly stressed components.
High-quality Haynes® 230 Sheets ready for industrial use.

Applications & Benefits
Why this grade
Haynes® 230 is a nickel-chromium-tungsten-molybdenum alloy with a lanthanum addition. It is the all-round choice in the range, combining creep strength and oxidation resistance to about 1150°C with the thermal stability and fabricability that older alloys such as Hastelloy X do not have, plus useful resistance to nitriding atmospheres.
- Chemical & Petrochemical: Catalyst grid supports in ammonia/nitric acid burners, high-temperature heat exchangers, ducts, bellows, and process internals where oxidation and nitridation are severe.
- Oil & Gas & Power: Combustion cans, transition ducts, flame holders, thermocouple sheaths, and hot-gas manifolds in gas turbines, plus superheater and reheater tubing in advanced ultra-supercritical boilers.
- Marine: High-temperature exhaust components and furnace fixtures that need better oxidation resistance than basic Ni–Cr alloys.
- Pharma: Clean, scale-resistant furnace baskets and fixtures supporting validated heat-treatment cycles.
- Industrial Heating: Furnace retorts, chains, fixtures, burner shrouds, recuperator internals, nitriding furnace internals, grates, trays, sparger tubes, cyclone internals, and thermocouple protection tubes.
- Hardware & OEM Stores: Stock Haynes 230 sheet metal for jet engine components and high-temperature fasteners to offer a premium upgrade over standard stainless and Nimonic 81 in static hot-zone parts.
