Tool steel is a type of high-quality carbon or alloy steel that is specifically designed for use in the manufacturing of tools and machinery parts. There are several different grades of tool steel, each with its own unique properties and applications. Some common grades include:
1. O-1 Tool Steel: This grade is known for its excellent hardness, wear resistance, and toughness. It is commonly used in making cutting tools, punches, and dies.
2. A-2 Tool Steel: A-2 grade offers good wear resistance and machinability. It is often used in applications requiring high production rates and precision, such as forming dies and precision measuring tools.
3. D-2 Tool Steel: D-2 grade is a high-carbon, high-chromium, and high-molybdenum steel. It exhibits excellent wear resistance and can retain its hardness even at high temperatures. It is widely used in making cutting tools, shear blades, and cold work punches.
4. H-13 Tool Steel: H-13 grade is a hot work tool steel with excellent heat resistance and high toughness. It is commonly used in applications that involve high temperatures, such as die casting, extrusion, and hot forging.
5. M-2 Tool Steel: M-2 grade is a high-speed tool steel known for its exceptional hardness and heat resistance. It is commonly used in making drills, reamers, and other cutting tools that require high-speed machining.
These grades are just a few examples, and there are many other tool steel grades available, each suited for specific applications. The choice of grade depends on factors such as the desired hardness, wear resistance, toughness, and the specific tool or part being manufactured.
Tool steel is a type of steel that is specifically designed to be used in the production of tools, dies, and other cutting or shaping instruments. There are several grades of tool steel, each with its own unique properties and applications. Some of the common grades include:
1. A2: This grade of tool steel is known for its excellent wear resistance and toughness. It is commonly used in applications such as blanking, forming, and trimming dies.
2. D2: D2 tool steel is highly wear-resistant and has good toughness. It is often used in applications that require high precision, such as thread rolling dies, forming rolls, and gauges.
3. M2: M2 is a high-speed steel grade that is known for its exceptional heat resistance and hardness. It is commonly used in cutting tools such as drills, taps, and milling cutters.
4. O1: O1 tool steel is known for its excellent machinability and good wear resistance. It is frequently used in applications such as punches, dies, and knives.
5. S7: S7 tool steel exhibits excellent impact resistance and is often used in applications that require high shock resistance, such as shear blades and hammers.
These are just a few examples of the various grades of tool steel and their applications. The choice of grade depends on factors such as the specific tooling application, required hardness, wear resistance, and toughness.
Tool steels are classified into different grades based on their chemical composition and properties. Some common grades include:
1. W-group tool steel: This grade includes water-hardening tool steels such as W1, W2, and W3. They are used for applications like punches, chisels, and woodworking tools.
2. O-group tool steel: Oil-hardening tool steels like O1, O2, and O6 belong to this grade. They offer high hardness, toughness, and wear resistance, making them suitable for cutting tools, punches, and dies.
3. A-group tool steel: Air-hardening tool steels like A2, A3, and A4 are part of this grade. They possess excellent toughness and wear resistance, making them ideal for forming tools, punches, and dies.
4. D-group tool steel: This grade includes high-carbon, high-chromium tool steels like D2, D3, and D6. They offer exceptional wear resistance and are commonly used for cutting tools, dies, and punches.
5. S-group tool steel: Shock-resisting tool steels like S1, S2, and S5 belong to this grade. They possess high impact resistance and are used in applications that involve heavy hammering or shock loads, such as hammers, chisels, and shear blades.
6. H-group tool steel: Hot-work tool steels like H11, H13, and H21 are part of this grade. They retain their hardness and strength at high temperatures, making them suitable for applications such as die casting, forging, and extrusion dies.
Each grade of tool steel has specific properties that make it suitable for different applications, allowing for the selection of the most appropriate grade based on the desired performance requirements.
