The temperature range of a vacuum annealing furnace is usually wide, generally between 300 ℃ and 1300 ℃, depending on the material being processed and the required heat treatment process.

300 ℃ to 600 ℃: Suitable for materials with low temperature sensitivity, such as certain metal alloys, which can be used to eliminate internal stresses generated during processing and improve their structure.

400 ℃ to 1100 ℃: Suitable for some common metal materials such as steel, copper, aluminum, etc. The specific annealing temperature range will vary depending on the composition, microstructure, and required performance requirements of the material. For example:

Low carbon steel and medium carbon steel: The annealing temperature is usually between 700 ℃ and 900 ℃ to improve their ductility and toughness.

High carbon steel: The annealing temperature may be higher, generally between 800 ℃ and 1000 ℃, to reduce hardness and improve machinability.

Copper and copper alloys: The annealing temperature is usually between 400 ℃ and 700 ℃ to eliminate stress and improve conductivity.

Aluminum alloy: The annealing temperature is generally between 300 ℃ and 500 ℃ to improve its mechanical properties and corrosion resistance.

600 ℃ to 1300 ℃: For some metal materials that require grain refinement and improved plasticity, higher annealing temperatures can be chosen.
