Properties of high speed steel and related applications
- High speed steel is a kind of tool steel with high hardness, high wear resistance and high heat resistance, its main performance characteristics are as follows
| Performance | Description |
| Hardness | After quenching and low-temperature tempering, the hardness is very high at room temperature, up to more than 60HRC |
| Wear resistance | Excellent abrasion resistance for cutting tools and molds |
| Heat resistance | Maintains good performance in high temperature environment, suitable for manufacturing tools and molds under high temperature conditions |
| Processability | Uniform alloy composition and simple heat treatment process, thus better workability |
- High-speed steels are used in a wide range of applications due to their excellent properties, as shown in the table below.
| Application area | Specific application |
| Metal processing | Cutting and processing of steel, alloys and other materials, manufacturing of cutting tools such as drills, milling cutters, lathes, taps, broaches, etc. |
| Die making | Manufacture of plastic injection molds, die-casting molds, stamping molds and precision molding dies, etc. |
| Precision parts processing | Manufacturing high-precision components for aerospace and automotive manufacturing |
| Thermoplastic forming | Manufacture of large tools and thermoplastic molding tools, such as extrusion molds, die casting molds, injection molds, etc. |
| Other industrial applications | It is also widely used in oil and gas extraction, heavy machinery manufacturing and other industrial fields that require high wear resistance and hardness. |
- To summarize, HSS plays an important role in many industrial fields by virtue of its excellent performance, especially in applications requiring high precision, high wear resistance and high temperature stability.
