There are a number of different grades of tool steel that differ based on the areas for which they are designed. These elements and their effects are discussed below. Most widely used in the A series. In selecting cold work tool steels, the metallurgical factors that ultimately affect tool performance and longevity must be considered. means that a given grade of tool steel should be heat-treated differently if it is to be used as a stamping tool versus a cutting tool. M42 tool steel is a molybdenum high speed tool steel with 8-10% cobalt added for increased hardness and hot hardness that is superior to other high speed grades. Some operate under cryogenic conditions. Before we can select the correct tool steel, first we must define what tool steel is. Include me in professional surveys and promotional announcements from GlobalSpec. BEST IDEAS. A2 has long been known as the classic standby for a fixed blade steel. Tool steel selection What are some of the pros and cons of different types of tool steels for making shop special jaws, v-block, general tooling type of stuff. This grade of tool steel is mainly used for items like cutting tools and drills, as well as knives and forks. Dimensions to consider include: Other specifications of importance (based on application) include product shape, tensile strength, yield strength, melting point, conductivity, corrosion resistance, ductility, and malleability. Please try again in a few minutes. AISI H-10, H-11, H-12, H-13 AISI H-19, H-21 H-13 is the most common hot working tool steel. Industrial Metal Supply offers tool steel bar in O-1 and A-2 grades. Tool steel grades are made specifically for different applications so it's good practice when selecting a grade to ask yourself a few questions first. Companies affiliated with GlobalSpec can contact me when I express interest in their product or service. These properties differ based on the metal or alloy composition. A variety of hot working steels can maintain a sharp cutting edge at much higher temperatures of up to 1000°C. 50-90% less linear size change in heat treat than tool steels . Improved SK105 grade for its hardenabillty. The AISI - SAE grades of tool steel is the most common scale used to identify various grades of tool steel. As a result tool steels are suited Cutting corners on the choice of material may not result in lower overall production cost if the tool proves to be inferior and fails prematurely. For a tool that has deformed under pressure, hardness should be increased. Some fail because of severe abrasive or adhesive wear, others fail because of cracking, chipping, or plastic deformation. Notify me about educational white papers. The AISI-SAE general purpose grades of tool steel are O-1, A-2, and D-2. Tool steel comparison chart, compare difference maker and standard. Call Today! A cost-benefit analysis should be undertaken to ensure that the tool steel material chosen will provide the performance required. Industrial Computers and Embedded Systems, Material Handling and Packaging Equipment, Electrical and Electronic Contract Manufacturing. Tool steels are only as good as the heat treat they receive. Search manufacturer catalogs by these specifications: I agree to receive commercial messages from GlobalSpec including product announcements and event invitations, Selecting metal alloys requires an analysis of the desired specifications. WORLD'S TO THE What is Tool Steel ? Selection of Cold Work Tool Steels. Choice of grade depends on whether a sharp cutting edge, impact resistance, or heat resistance is most important, and also on what machining and hardening processes are being utilized. 2.

To qualify as a high-speed steel, the chemical composition must meet certain minimum requirements, which are defined in the ASTM A600 Specification for High-Speed Tool Steels. Fixturing. This results in a sharper cutting edge that lasts longer, even when being used to machine high-hardness and hard-to-machine alloys in heavy duty and high production applications. Compare grades using mechanical properties including abrasion resistance, toughness, size stability, machinability and grindability. Choice of grade depends on whether a sharp cutting edge, impact resistance, or heat resistance is most important, and also on what machining and hardening processes are being utilized. Its ability to hold a keen cutting edge, resistance to abrasion and wear, and deep-hardening properties, A2 exceeds the regular oil-hardening grades. Tool steels fails in different ways. A tool that has become worn to failure needs a tool steel with greater wear resistance. Tool Steel Selection. The higher carbon and chromium levels in D-2 steel make it a good choice for applications requiring a longer tool life. It is safer in hardening and has less distortion in heat-treating than the oil-hardening types. This high-speed, tool grade steel is used primarily in cutting tools in industrial applications. Our products are always state-of-the-art. Some may have superior thermal shock resistance. cold-work tool steels, high-speed tool steels, and hot-work tool steels. Its ability to hold a keen cutting edge, resistance to abrasion and wear, and deep-hardening properties, A2 exceeds the regular oil-hardening grades. This is why it’s so important to understand the properties of different tool steels, as well as other factors such as the geometry of the die, the material being worked, and the manufacturing history of the tool itself. O-1 is an oil-hardening steel with high hardness and good machinability. There are a number of different grades of tool steel that differ based on the areas for which they are designed. A-2 is an air-hardening steel containing a medium amount of alloying material (chromium). A final issue to consider when selecting a tool steel grade is cost. Tool steel is known for its extreme hardness, as well as it abrasion resistance and ability to hold a cutting edge at high temps. Tool steel bar is, as the name suggests, often used to produce tools (among other applications). Hot Working Tool Steels. Low-carbon steels such as 1018 and A36 fall into the P1 category, while P6 includes PH (precipitation hardening) and 400-series stainless steels (440C, 15-5, … 1095 is budget-friendly and widely available. D-2 steel can be either oil-hardened or air-hardened, and contains a higher percentage of carbon and chromium than O-1 and A-2 steel. as well as subscriptions and other promotional notifications. All of these tool steels use a substantial amount of carbide forming alloys. Advantage Tool Steel supplies tool steel in both rounds and flats. Press forming dies, jigs and tools, gauges. Tool Steel Grades, Applications and Production Methods Tool steels are yet another classification or type of metal you can find on the market. Typical applications of A-Grade tool steel include Arbors, Cams, Die Bending, Blanking, Coining, Embossing, Cold Forming, Lamination, Cold Swaging, Cold Trimming, Gages, Chipper Knives, Cold Shear knives, Woodworking Knives, Lathe Center Knives. An understanding of these tool steel properties and related issues permits selection of the optimum steel for most applications. They exhibit good hardness, abrasion resistance, and deformation resistance. Before selecting a tool steel grade, it’s important to consider which type of tool failure is most likely for this application by examining failed tools. The lowest alloy grades, M50 and M52 high-speed steels, are properly known as intermediate high-speed steels because of their lower alloy contents. Their suitability comes from their distinctive hardness, resistance to abrasion and deformation and their ability to hold a cutting edge at elevated temperatures. Tool steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. Though selecting a tool steel may seem straightforward, the process requires tradeoffs – making the task an art as well as a science. Cold work tool steels are designed for tooling applications where the service temperature is under about 600°F (316°C). Grade Description; A-2: Air-hardening steel.
