Product Description
- Aluminum-containing nickel-chromium heat-resistant alloy Inconel 601 (UNS N06601, EN standard 2.4851)
- Forms dense self-repairing Al₂O₃ film for ultra-high anti-oxidation performance up to 1200°C
- Excellent resistance to thermal cycling, anti-scaling & anti-spalling under repeated heating & cooling
- Outstanding anti-carburization & anti-nitriding capacity for heat treatment furnace equipment
- Balanced room & high-temperature mechanical strength, stable creep resistance at elevated temperature
- Good ductility and reliable weldability without sensitization after long-time thermal exposure
- Custom hot forging, hot rolling and full CNC precision machining per customer CAD drawings
- Manufactured strictly complying with ASTM B166 international alloy bar standard
- Long service life for industrial furnace, automotive exhaust and nitric acid equipment parts
This series of Inconel 601 round bars are hot forged & hot rolled solid nickel-chromium-aluminum alloy rods. After complete solution annealing and stress relief heat treatment, the material obtains uniform single-phase austenite grain structure, stable dimensional tolerance and excellent high-temperature comprehensive performance.
Inconel 601 is specially optimized for high-temperature oxidation service. The added aluminum element generates compact alumina protective layer, which solves the peeling problem of pure chromium oxide film under thermal cycles. It far surpasses Inconel 600 in furnace radiant tubes, heat treatment fixtures and high-temperature exhaust components, and maintains stable performance in nitric acid and mild corrosive environments.
- Ni-Cr-Al solid solution strengthened heat-resistant alloy with controlled aluminum content
- Superior cyclic oxidation resistance, no oxide layer peeling under frequent temperature fluctuation
- Strong resistance to carburizing, nitriding and sulfur-containing high-temperature atmospheres
- Retain stable tensile & creep strength at 900–1200°C continuous working temperature
- Good cold & hot forming performance, easy for stamping, bending and complex machining
- Low carbon design avoids intergranular carbide precipitation after welding & heating cycles
