INCONEL 602CA（UNSN06025） Bar/Rod
Nickel-Chromium-Iron-Aluminum-Yttrium Alloy for High-Temperature Oxidation Resistance
INCONEL 602CA bar is commonly used for machined components such as valve parts, pump shafts, fasteners, flanges and fittings where broad corrosion resistance is required. The alloy provides outstanding resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, and offers excellent weldability and fabrication characteristics for critical chemical process equipment.
As a professional Chinese nickel-based alloy manufacturer, we supply INCONEL 602CA in multiple product forms with stable chemistry, consistent mechanical properties, and flexible dimensional customization for global industrial users.
Typical supply range (custom sizes and tolerances available upon request):
Item | Range / Options | Notes |

Length | Up to 6000 mm | Cut-to-length (sawing) by agreement; define tolerance if critical. |
Shape | Round / Square / Flat / Hex | Forged / hot-rolled / cold-drawn per size requirement. |
Surface finish | Black / Peeled / Ground / Polished | Surface machining available for tight tolerance. |
End | Saw-cut / Facing / Chamfer | End prep available for machining and assembly. |
Straightness / tolerance | Per ASTM/EN or as agreed | Define straightness for long shafts and precision parts. |
Delivery condition | Solution annealed (standard) | Annealed & pickled/bright depending on size/finish. |
Dimension definition: DIA × LENGTH.
• Excellent resistance to pitting and crevice corrosion in chloride media
• Outstanding resistance to chloride stress corrosion cracking (SCC)
• Strong resistance to oxidizing and reducing acids in mixed process media
• Withstands wet chlorine gas, hypochlorite, and chlorine dioxide solutions
• High chromium content improves resistance to oxidizing media; suitable for use in the as-welded condition
• Good fabrication and welding performance for CPI equipment
