Inconel 690 Wire Supplier, Stockist and Exporter
Table of Contents
Aurico Alloys LLP supplies Inconel 690 wire (N06690, Werkstoff 2.4642) to ASTM B166 from Mumbai, to customers across India and in more than 40 export markets.
Wire in 690 is bought where the rest of the equipment is already in 690 or in a comparable high-chromium alloy: supports, ties, mesh and baskets inside nitric acid and pickling plant, and wire parts exposed to hot oxidising gas. The wire has to resist the same chemistry as the vessel around it, and in oxidising acid that means chromium.

Composition limits for Inconel 690. 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
Properties follow the temper ordered, and the certificate states the tensile result for the temper supplied. Annealed 690 runs around 590–760 MPa tensile; its value in wire form is resistance to oxidising acids and hot oxidising gas.
Industry Applications
Why Inconel 690 wire
For wire parts in oxidising service, the argument is the same as for the vessel: 27–31% chromium. For welding 690, order the wire as filler metal – Special Metals produces a matching filler for 690 structures, and welding consumables are certified to their own classification rather than to ASTM B166, so say at enquiry which you need.
| Industry | Typical use |
|---|---|
| Chemical processing | Supports, ties and mesh in nitric acid equipment. |
| Metal finishing | Pickling baskets and hangers in nitric-hydrofluoric service. |
| Power generation | Wire parts exposed to hot, sulphur-bearing combustion gas. |
| Fabrication | Filler for welding 690, ordered as a welding consumable. |
Testing and Certification
Every coil or spool is traceable to its heat on an EN 10204 3.1 mill test certificate stating chemical analysis and the tensile result for the temper supplied. Diameter is checked against the ordered tolerance, and positive material identification and third-party inspection are available under our ISO 9001:2015 system.
