Should I choose Inconel 600 steel plate or Inconel 601 steel plate?
If your application requires superior high-temperature performance, especially excellent oxidation and carburization resistance, choose Inconel 601 sheets; while Inconel 600 sheets are suitable for general high-temperature applications requiring good corrosion resistance and high tensile strength. Because Inconel 601 sheets have added aluminum, their oxidation resistance is improved, making them more suitable for high-temperature environments.
What are the temperature limits for Alloy 601?
1600-2250°F (870-1230°C)
The hot forming temperature range for Alloy 601 is 1600-2250°F (870-1230°C). Hot working operations involving large deformations should be performed at 1900-2250°F (1040-1230°C). This alloy exhibits poor ductility in the temperature range of 1200 to 1600°F (650-870°C) and should not be processed within this temperature range.
Inconel 600 and Inconel 601 sheets are two commonly used nickel-based alloy sheets widely applied in numerous fields. Although they belong to the same nickel-based alloy family, they differ significantly in composition, properties, and applications. A thorough understanding of these differences is crucial for the correct selection and use of these two materials.

Corrosion Resistance Comparison: UNS N06600 vs UNS N06601 Plate
| Corrosion Resistance Aspect | UNS N06600 (Alloy 600) Plate/Sheet | UNS N06601 (Alloy 601) Plate/Sheet | Comparison Summary |
|---|---|---|---|
| General Corrosion Environment Tolerance | Good tolerance in many conventional corrosion environments | Good tolerance in many conventional corrosion environments | Both alloys exhibit good performance in common corrosive settings |
| Chloride Stress Corrosion Cracking (SCC) Resistance | Good resistance to chloride SCC | Slightly better resistance to chloride SCC | 601 outperforms 600 due to the synergistic effect of Cr and Al in its composition |
| High-Temperature Oxidation Resistance | Good oxidation resistance up to ~1095°C (2000°F) | Significantly better oxidation resistance | 601's high Cr (21–25%) and Al addition enable formation of a denser, more stable oxide film at high temperatures |
| Primary Corrosion Advantage | Balanced resistance in oxidizing and reducing environments; good chloride SCC resistance | Superior high-temperature oxidation and scaling resistance; slightly better chloride SCC resistance | 601 excels in high-temperature oxidizing environments; 600 is more versatile in mixed environments |
