M2Ai is a cobalt-free and aluminum-containing super-hard high-speed steel. Vacuum heating promotes abnormal grain growth. Filling inert gas for vacuum heating can increase the heating speed, hinder the formation of abnormally large grains, and improve the strength and toughness of M2Ai steel. Influence
The most important factor in the strength and toughness of M2Ai steel is not the size of mixed crystals and austenite grains, but the shape and distribution of carbides in the steel. In order to take advantage of the super hardness of M2Ai steel, the vacuum quenching temperature can be increased to make the hardness reach above 66HRC.
Recommendation: The hardness of the processed material should be within 32 degrees (4 blades are suitable for flat corners, 3 blades are suitable for aluminum products, and 2 blades are suitable for keyways)
