It should be noted that many powder metallurgy high-speed steel producers do not adopt process measures to improve material purity in order to reduce costs. The steel they produce may contain many impurities that cause micro-cracking of the tool. However, it is difficult to discern the quality of the product based on the product information provided by the manufacturer. The user must ask the manufacturer to explain the process measures for removing impurities, or further require it to provide detailed technology on the size of impurities in the steel. data.
The powder metallurgy process changes the material properties of traditional high-speed steel, especially with the newly developed purification technology, which enables powder metallurgy high-speed steel to achieve extremely high alloy content while maintaining its toughness. Therefore, the cutting performance of powder metallurgy high speed steel tools surpasses traditional high speed steel tools in almost all cutting fields, and is superior to solid carbide tools in high cutting rate and high impact cutting. Although its price is higher than that of ordinary high-speed steel, it can be compensated for by improving the performance of the tool, prolonging the life, and improving the wearability.
