SKH57 tungsten high-speed steel and powder metallurgy tool steel.
SKH57 tungsten high-speed steel is a tool steel with high hardness, high wear resistance and high heat resistance, which is often used in the manufacture of cutting tools, stamping dies, drills and other high-strength and high-wear-resistant mechanical parts. Powder metallurgy tool steel is a kind of tool steel prepared by powder metallurgy process, which has the characteristics of high hardness, high wear resistance, high impact resistance and high toughness, and is widely used in the manufacture of cutting tools, molds, wear-resistant parts, etc.
SKH57 tungsten high speed steel and powder metallurgy tool steel use different processes and materials in the manufacturing process, so there are certain differences in their properties and applications.
First of all, SKH57 tungsten series high-speed steel is prepared by a traditional melting and casting process. In the manufacturing process, tungsten, chromium, molybdenum and other alloying elements are first smelted into molten steel, and then casting, rolling, heat treatment and other processes are used to finally obtain high-performance steel. This steel has high hardness and wear resistance, as well as good heat resistance and toughness. Therefore, SKH57 tungsten series high-speed steel is suitable for manufacturing cutting tools, drills, stamping dies, etc., which need to withstand high loads, high friction and high impact.
Whereas, powder metallurgy tool steel is prepared by powder metallurgy process. Powder metallurgy is an advanced metal preparation technology, through the metal powder smelting, atomization, pressing and sintering and other processes, to obtain dense metal materials. In the manufacturing process of powder metallurgy tool steel, the alloying element powder is first mixed evenly, then the billet is obtained by pressing and sintering, and finally the final product is obtained through processing and heat treatment. Because the powder metallurgy process can precisely control the composition and microstructure of the material, powder metallurgy tool steel has the advantages of high hardness, high wear resistance, high impact resistance and high toughness. This steel is suitable for the manufacture of cutting tools, molds, etc., which need to withstand high loads, high friction and high-speed cutting.
Secondly, in terms of application, SKH57 tungsten high-speed steel is mainly used in the manufacture of cutting tools, stamping dies, drill bits and other mechanical parts. Due to its high hardness and wear resistance, these parts are guaranteed to remain sharp and resistant to wear and tear over long periods of use. At the same time, because it also has good heat resistance and toughness, it can withstand high temperature and impact force, and is suitable for various complex working environments.
Powder metallurgy tool steels are widely used in the manufacture of cutting tools, molds and wear parts. Due to its excellent mechanical properties and wear resistance, it can ensure that cutting tools and dies maintain accuracy and performance during long-term use. At the same time, because it also has good toughness and impact resistance, it can withstand large impact forces and pressures, and is suitable for various complex working conditions.
In conclusion, SKH57 tungsten high-speed steel and powder metallurgy tool steel are both high-performance tool steel grades, and they have certain differences in manufacturing process, performance and application. According to different use needs, you can choose the right tool steel grade to meet the manufacturing requirements of various mechanical parts.
