What are the basic requirements for tool materials? At the same time, in order to avoid affecting the thinking downstairs and to facilitate grading, please hide your replies.

The basic requirements for tool materials are as follows: ①High hardness: ②Sufficient strength and toughness ； ③High wear resistance ； ④High heat resistance ； ⑤Good craftsmanship.
1. Introduction to tool materials. Tool materials have a great impact on the life of the tool, processing quality, cutting efficiency and manufacturing cost. The cutting part of the tool must withstand high temperature, high pressure, strong friction, impact and vibration during cutting. 2: The basic requirements for the material performance of the cutting part of the tool are ① high hardness; ② high wear resistance; ③ high heat resistance (thermal stability) ④ sufficient strength and toughness; ⑤ good processability. 3: Tool materials are: Carbon tool steel, alloy tool steel, high-speed steel, carbide, ceramic, diamond, cubic boron nitride, carbon tool steel (such as T10A, T12A) and alloy tool steel (such as 9SiCr, CrWMn), due to poor heat resistance - usually only used for hand tools and tools with low cutting speeds. Ceramics, diamond and cubic boron nitride are currently only used in more limited occasions, high-speed steel and carbide - the most widely used.
A: High hardness B: High wear resistance C: Sufficient strength and toughness D: Good heat resistance (thermal stability) E: Good forging performance, heat treatment performance, welding performance, grinding performance and other process properties.
Good hardness, good strength, good forgeability, good toughness, good grindability, wear resistance, good wear resistance, good cutting performance

Tool material refers to the material of the cutting part. It works at high temperatures and has to withstand greater pressure, friction, impact and vibration, etc., so it should have the following basic properties: (1) Higher hardness The hardness of the tool material must be higher than the hardness of the workpiece material, and the hardness at room temperature is generally above 60HRC. (2) It has sufficient strength and toughness to withstand cutting force, impact and vibration. (3) It has good wear resistance to resist wear during the cutting process and maintain a certain cutting time. (4) Higher heat resistance, so that it can maintain higher hardness at high temperatures, also known as red hardness or hot hardness. (5) It has good craftsmanship to facilitate the manufacture of various cutting tools. Technological properties include forging, rolling, welding, cutting, grinding and heat treatment properties. At present, there is no tool material that can fully meet the above requirements. Therefore, it is necessary to understand the properties and characteristics of commonly used tool materials in order to select appropriate tool materials based on the performance and cutting requirements of the workpiece material.
Corrosion-resistant, with certain hardness and wear resistance.
①High hardness; ② High wear resistance; ③ High heat resistance (thermal stability) ④ Sufficient strength and toughness; ⑤ Good processability.
