CPM REX 20 powder high-speed steel is a high-performance metal material with excellent hardness and wear resistance, which is widely used in the manufacture of high-precision, high-strength, and high-wear-resistant mechanical parts such as knives and cutting tools. The following will introduce the features and benefits of CPM REX 20 powder high speed steel from different perspectives.
1. Composition and organization.
CPM REX 20 powdered high speed steelIt is a steel grade containing a high proportion of tungsten, molybdenum, chromium, vanadium and other alloying elements, which form carbides and intermetallic compounds in steel, giving it excellent hardness and wear resistance. Its structure is martensite and bainite, with the characteristics of high density and high hardness, and after heat treatment, its hardness can reach HRC65-70, with extremely high wear resistance and cutting performance.
Second, performance characteristics.
CPM REX 20 powdered high speed steelCPM REX 20 powder high speed steel has:
1.High hardness: After heat treatment, its hardness can reach HRC65-70, with extremely high wear resistance and cutting performance.
2.High strength: Its tensile strength can reach more than 2000MPa, and it has excellent toughness and impact resistance.
3.Excellent cutting performance: Because of its high hardness, high strength and excellent toughness, it has excellent cutting performance and can be widely used in the manufacture of mechanical parts such as tools and cutting tools.
4.Good heat treatment properties:CPM REX 20 powdered high speed steelIt has good heat treatment performance, and can obtain higher hardness and strength after heat treatment.
5.Excellent wear resistance: Due to its high proportion of alloying elements, carbides and intermetallic compounds are formed, giving it excellent wear resistance.
Third, the field of application.
CPM REX 20 powdered high speed steelIt is widely used in the manufacture of high-precision, high-strength, and wear-resistant mechanical parts such as cutters and cutting tools, such as milling cutters, drills, taps, etc. In addition, it has a wide range of applications in automotive, aerospace, energy and other fields.
4. Precautions for use.
in useCPM REX 20 powdered high speed steel, you need to pay attention to the following:
1.Reasonable selection of heat treatment process:CPM REX 20 powdered high speed steelDifferent hardness and strength will be obtained after different heat treatment processes, so it is necessary to choose a reasonable heat treatment process according to the use requirements.
2.Take care to prevent cracking: due toCPM REX 20 powdered high speed steelIt has the characteristics of high strength and hardness, and it is easy to crack during manufacturing and use, so it is necessary to pay attention to prevent cracking.
3.Maintain good grinding performance:CPM REX 20 powdered high speed steelIt has good grinding performance, but it is necessary to pay attention to maintaining the rationality and stability of grinding parameters during the grinding process to avoid the occurrence of grinding cracks.
4.Pay attention to precautions: due toCPM REX 20 powdered high speed steelWith the characteristics of high hardness and high strength, it is necessary to pay attention to protective measures in the process of manufacturing and use to avoid harm to the human body.
In short,CPM REX 20 powdered high speed steelIt is a high-performance metal material with excellent hardness and wear resistance, and is widely used in the manufacture of high-precision, high-strength, and high-wear-resistant mechanical parts such as knives and cutting tools. In the process of use, it is necessary to pay attention to the reasonable selection of heat treatment process, prevention of cracking, maintaining good grinding performance and paying attention to protective measures.
