Features
① Series (type) high-speed tool steel is the most common, especially used in large quantities in the world to replace type high-speed tool steel
② Carbide structure is fine Neatly distributed and well distributed. And the organization is uniform. Therefore, the wear resistance and toughness are relatively balanced. Especially because it is only an increase or decrease in carbon content, it can continuously and significantly change the properties of steel without damaging the high-temperature properties. When toughness is required, low carbon steel is suitable. When hardness and wear resistance are required, high carbon steel is suitable.
③It is rich in hot and cold working plasticity and has good machinability and grindability.
Uses
Cutting
Drills, taps, reamers, circular saws, gear cutters, broaches, planers, etc.
Molds are used
Various hot-working and cold-working dies, punches, cutting knives, strip knives, various gadolinium roller tools, etc.
Japan's Hitachi Yasui Steel belongs to cold mold tool steel, also known as Japan's Hitachi special high-speed high-speed mold steel containing tungsten content above
Comparative standards and characteristic chemical composition analysis results
Chromium under carbon and molybdenum sulfur< br/> Steel properties: Wear resistance, toughness, high hardness, high-speed steel
Steel is generally used for manufacturing powerful cutting and wear-resistant advanced poppet molds. Screw molds require toughness and complex shapes, milling cutters, drill bits, etc.
