Alloy 602 CA Wire Supplier, Stockist and Exporter
Table of Contents
Aurico Alloys LLP supplies alloy 602 ca wire (N06025, Werkstoff 2.4633) from ready stock in Mumbai, to customers across India and in more than 40 export markets.
Wire is bought on diameter tolerance and temper, and for welding, spring and mesh work those two properties matter more than anything on the certificate.
Alloy 602 CA combines an alumina scale with carbide strengthening, so it keeps creep strength at temperatures where alloy 601 has already softened.

Composition limits for 602 CA. 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
The carbide dispersion plus the alumina scale give the highest creep-rupture strength of the alloy 600 family, with oxidation and carburisation resistance to 1200°C.
Industry Applications
| Industry | Typical use |
|---|---|
| Heat treatment | Furnace rollers, radiant tubes and load-bearing fixtures above 1100°C. |
| Petrochemical | Steam reformer and cracking-furnace hardware. |
| Power generation | Waste incineration and biomass combustion components. |
| Chemical processing | Carburising and nitriding atmosphere equipment. |
| Industrial heating | Burner components and high-temperature ducting. |
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 the specification we can add positive material identification, ultrasonic and dye-penetrant testing, intergranular corrosion testing to ASTM G28 or A262, and third-party inspection release from Lloyd's Register, Bureau Veritas, SGS or TUV.
Aurico Alloys LLP operates an ISO 9001:2015 quality management system, and can certify material to NACE MR0175 / ISO 15156 for sour service where the grade permits.
