Powder metallurgy high speed steel is a kind of high speed steel, which is made by atomizing high speed steel with high pressure inert gas or high pressure water, then pressing under high temperature and high pressure, and then sintering. The latest progress in the preparation technology of ZHONGwei precision powder metallurgy high speed steel further enhances the competitiveness of powder metallurgy high speed steel. The application of electroslag heating (ESH) refining process is a milestone for powder metallurgy high speed steel. Zhongwei precisely knows that this process can remove almost all impurities in the steel, further strengthen the toughness of the material, and significantly improve the anti chipping ability of the tool. In addition, due to the reduction of impurities in the steel, Zhongwei Precision can further increase the alloy content in the steel. For example, the vanadium carbide content of a certain powder metallurgy high-speed steel grade can reach 14%, while the maximum vanadium carbide content of ordinary high-speed steel grade is only about 4%. Although a large amount of alloy is added to the steel, its toughness and grindability will not be affected.

With the newly developed purification technology, the powder metallurgy high speed steel can reach extremely high alloy content while maintaining its toughness. Therefore, the cutting performance of powder metallurgy high-speed steel tools has surpassed that of traditional high-speed steel tools in almost all cutting fields, and is superior to that of solid carbide tools in high cutting rate and high impact machining. Although its price is higher than that of ordinary high speed steel, it can be compensated by the improvement of tool performance, the extension of service life and the improvement of grindability. The application prospect of powder metallurgy high speed steel in tool industry is very promising, and more and more people pay attention to it.
