Inconel 693 Coil Supplier, Stockist and Exporter
Table of Contents
Aurico Alloys LLP supplies Inconel 693 coil, sheet and slit strip (UNS N06693) to ASTM B168 and B906 from Mumbai, to customers across India and in more than 40 export markets.
Flat 693 is bought for the parts inside a synthesis-gas unit that are made from sheet rather than tube: baffle plates, shrouds and liners, which Special Metals records as fabricated from the alloy. It is also one of the two typical product forms – strip and tube – for high-temperature fuel cell designs that produce synthesis gas, where the same metal-dusting risk applies.

Mechanical and Physical Properties
Sheet and strip are supplied annealed for forming. The value of 693 in flat form is its chromium and aluminium scale, which resists metal dusting and carburisation on parts that would otherwise be eaten from the surface.
Industry Applications
Why Inconel 693 coil
A baffle or a liner in synthesis gas fails the same way a tube does – locally, by metal dusting – and replacing it in the same alloy repeats the failure. 693 sheet stops the mechanism rather than delaying it. Coil makes sense for fuel cell and heat-exchanger components produced in volume, where consistent gauge along the run matters; for one-off baffles, cut sheet is the practical choice.
| Industry | Typical use |
|---|---|
| Petrochemical | Baffle plates, shrouds and liners in synthesis-gas equipment. |
| Energy | Strip for high-temperature fuel cell components in synthesis-gas service. |
| Chemical processing | Formed parts in carburising process gas. |
| Heat treatment | Sheet-metal parts in carbon-rich furnace atmospheres. |
Testing and Certification
Coil is supplied with an EN 10204 3.1 mill test certificate stating heat number, chemical analysis, mechanical properties and temper. Thickness and width are checked against the order, and positive material identification and third-party inspection are available under our ISO 9001:2015 system.
