I. Overview of Inconel 601 (N06601) nickel-based alloy:

Inconel 601 (UNS N06601) is a high-temperature nickel-based alloy with a chromium content of 21.0-25.09% and a nickel content of about 72%. Inconel 601 (UNS N06601) has strong oxidation resistance, high-temperature resistance, and corrosion resistance, and it also has high mechanical properties at elevated temperatures. Inconel 601 (UNS N06601) has high-temperature strength and excellent oxidation resistance, carburization resistance, and sulfidation resistance. Especially in environments with severe temperature fluctuations and repeated oxidation, it exhibits excellent oxidation spall resistance, making it widely used in various components of heat treatment furnaces, diesel vehicle glow plug components, etc.

V. Processing and heat treatment of Inconel 601 (N06601) nickel-based alloy:

Inconel 601 (UNS N06601) nickel-based alloy does not belong to the category of precipitation hardening alloys, so it cannot be age-hardened through heat treatment. After cold working, when the temperature reaches around 900°C, the material softens. If high-temperature strength is required, it is recommended to perform solution heat treatment at temperatures of 1100 to 1200°C. The cooling method should use water cooling, and depending on the thickness of the plate, air cooling may also be used. However, to avoid carbide precipitation, it is recommended to cool as quickly as possible within the temperature range of 500 to 800°C.

VI. Formability of Inconel 601 (N06601) nickel-based alloy

Inconel 601 (UNS N06601) nickel-based alloy is relatively easy to process thermally. The heating temperature is 1150 to 1200°C, and the hot working temperature is 1050 to 1200°C. Simple processing can be done below 850°C. Cracking may occur in the temperature range of 650 to 850°C, so it is essential to avoid processing in this temperature range. Regarding cooling after hot working, to avoid carbide precipitation, it is recommended to increase the cooling rate within the range of 500 to 800°C. Alloy 601 has excellent cold workability and can be processed similarly to SUS 310S and Alloy 800.
