Can a vacuum annealing furnace anneal metal workpieces?

　　Vacuum annealing furnace is mainly used for heat treatment of metal materials such as stainless steel, titanium alloy, nickel based alloy, etc. in vacuum or protective atmosphere, including annealing, solid solution, aging and other processes. Annealing is an important process aimed at changing the microstructure and properties of metal workpieces through heating and slow cooling, in order to eliminate stress, improve toughness, and enhance cutting performance. Annealing treatment in a vacuum environment can prevent metal workpieces from reacting with oxygen in the air, thereby preventing adverse phenomena such as oxidation and decarburization. This helps to maintain the surface smoothness and internal structural stability of metal workpieces. Therefore, vacuum annealing furnace is an effective equipment for annealing metal workpieces, widely used in various fields such as aerospace, automotive, electronics, medical, etc.
