1. Composition: Carbon tool steel has a higher carbon content, while high-speed steel has a lower carbon content but more alloying elements.
2. Hardness: The hardness of carbon tool steel generally reaches 58~65HRC, while the hardness of high-speed steel is around 63HRC.
3. Wear resistance: Carbon tool steel has better wear resistance, while high-speed steel is better at cutting and has relatively weak wear resistance.
4. Processing performance: Carbon tool steel has poor processing performance, while high-speed steel has good processing performance.
5. Application fields: Carbon tool steel is widely used in the manufacture of cold work dies, hot work dies, cutting tools, etc., while high-speed steel is mostly used in the manufacture of high-speed cutting tools, milling cutters, turning tools, drill bits, etc.
Carbon tool steel and high-speed steel are common types of steel. Depending on their composition, hardness, wear resistance, processing performance, etc., their application ranges are very different. When selecting materials, you need to choose according to the specific application scenario to achieve the best use effect.
