The difference between Inconel 600/601 alloy plates and sheets.
The difference between Inconel 600/601 alloy plates and sheets
Both Inconel 600 and 601 are nickel-chromium alloys, but Inconel 601 contains added aluminum, which significantly improves its high-temperature oxidation and carburization resistance, making it more suitable for extreme high-temperature applications than Inconel 600. Inconel 600, on the other hand, possesses excellent strength and good corrosion resistance, particularly in its resistance to stress corrosion cracking. The main difference between the two lies in the higher thermal stability of Inconel 601 due to its aluminum content, making it more suitable for long-term high-temperature use, while Inconel 600 exhibits good mechanical properties over a wider temperature range.
What are the uses of Alloy 600?
Alloy 600 is used in numerous fields, including chemical and food processing, heat treatment, phenol condensers, soap manufacturing, and containers for vegetable oils and fatty acids. It exhibits good corrosion resistance to a variety of corrosive media.

Summary of the main differences between Inconel 600 and 601 plates:
Oxidation resistance: Due to the presence of aluminum, the oxidation resistance of 601 plates is significantly better than that of 600 alloy plates.
Temperature range: 601 alloy plates perform excellently in extremely high-temperature ranges, while the performance of 600 plates deteriorates in this temperature range.
Applications: 600 alloy plates are suitable for applications requiring general strength, while 601 alloy plates are suitable for harsh high-temperature/oxidizing environments.
