Application of vacuum quenching furnace

M2 high-speed steel is a widely used general-purpose high-speed tool steel, belonging to the molybdenum-type high-speed steel family. High Hardness: After heat treatment, it can achieve a very high hardness. High Wear Resistance: Containing high levels of alloying elements such as carbon, molybdenum, tungsten, and vanadium, it possesses excellent wear resistance. Excellent Red Hardness: This is one of the most important characteristics of high-speed steel. "Red hardness" refers to the ability to maintain high hardness and cutting performance even when subjected to high temperaturesduring high-speed cutting. M2 excels in this aspect. The following is the process flow for vacuum quenching and vacuum tempering required to obtain M2 high-speed steel:  1.Preheating Stage First Preheating: Temperature controlled between 550°C and 650°C, holding time approximately 10 to 20 minutes after furnace through-heating. Second Preheating: Temperature raised to between …
