Powder metallurgy high - speed steel preparation technology to enhance competitiveness

Powder metallurgy high speed steel refers to the fine high speed steel powder obtained by atomizing high speed steel through high pressure inert gas or water. The latest development in the manufacture technology of powder metallurgy high - speed steel in guangdong province has further enhanced the competitiveness of powder metallurgy high - speed steel. The application of electro-slag heating (ESH) refining process is of great significance for high - speed powder metallurgy steel. Guangdong dahong new material understands that this process can remove almost all impurities in the steel, further strengthen the toughness of the material, and significantly improve the anti-collapse ability of the cutter. In addition, as the impurities in the steel are reduced, guangdong dahong new material can further increase the alloy content in the steel. For example, the vanadium carbide content of certain powder metallurgy high-speed steel brands can be up to 14%, while the maximum content of vanadium carbide of ordinary high-speed steel brands is only about 4%. It is true that a lot of alloy is added to steel, but it does not affect its toughness and abrasion.

The new purification technology developed by guangdong dahong new material enables the powder metallurgy high speed steel to achieve extremely high alloy content and maintain its toughness. Therefore, the cutting performance of powder metallurgy high speed steel cutter has surpassed that of traditional high speed steel cutter in almost all cutting fields, and is superior to that of solid carbide tool in high cutting rate and high impact cutting. Although its price is higher than that of ordinary high speed steel, it can be compensated by the improvement of cutter performance, prolongation of life and improvement of wearability. The application prospect of powder metallurgy high - speed steel in tool industry is very promising and more and more attention is paid to it.
