Application of high-speed steel
Are you interested in the use of high-speed steels from the supplier AvecGlob? Here you will find interesting information on this topic.
Properties of high-speed steels
High-speed steels have the following features:
- The increased content of tungsten, which increases the resistance of steel in conditions of intense abrasion and sufficiently high contact temperatures;
- The minimum amount of bound oxygen, which increases the mechanical strength;
- The coarse-grained microstructure is sufficiently large, which forces, after heat treatment, leveling annealing, as a result of which initially high hardness decreases somewhat;
- The presence of cobalt, which increases the so-called «hot hardness» steel;
- Mandatory pre-annealing before quenching, as a result of which the structure of high-speed steels becomes more fine-grained, and their plasticity and hardness increase.
The abundance of alloying elements gives high-speed steels also enhanced corrosion resistance properties.
Supplier — AvekGlob company — offers at a reasonable price from the manufacturer a diverse range of high-speed steels that meet the technical requirements of domestic and foreign standards. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Application
Due to their performance characteristics — high hardness, heat resistance, anticorrosive parameters — high-speed steels are used not only for their direct purpose (as a metal cutting tool for machining hard-to-process steels and alloys), but also for the production of an unstressed stamping tool operated in high conditions specific efforts. High-speed steels also produce bearing housings.
Summary table of applicability of various brands of high-speed steels of domestic production:
| steel grade | Features and conditions of work | Appointment |
| P18 | The tool with high wear resistance, retains cutting properties when heated up to 600 ° C | Cutters, drills, cutters, trimmers, sweeps, countersinks, taps, broaches |
| P9 | Works with heating the cutting edge to 600 ° C, does not require significant grinding and sharpening. It is possible to use methods of hot plastic deformation and induction hardening. | Cutters, drills, cutters, saws, woodworking tools, hacksaws, shears of shears |
| P12 | It works when the cutting edge is heated to 600 ° C, a considerable amount of grinding is possible. Hot plastic deformation can be used | Cutters, drills, cutters, trimmers, sweeps, taps, broaches, dies, punches |
| P6M5 | Works with heating up to 580−600 ° C, with large feeds in conditions of increased mechanical and impact loads. The application of methods of hot plastic deformation | Cutters, worm cutters, drills, broaches, machine taps, punches, dies, bearings |
