Industrial Metal Supply offers a variety of shapes and sizes of tool steel bar in O-1 and A-2 grades. Maintenance is the variable I focus on most in the steel-selection process. A tool that has become worn to failure needs a tool steel with greater wear resistance. ... Powder metallurgy cold-work tool steels offer superior wear resistance compared with conventional tool steel grades, and have good strength and toughness characteristics. 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. Cold Work. For example, some tooling fails due to abrasive wear, in which the material being cut wears down the tool surface, though this type of failure is slow to occur and can be anticipated. Because tool steels have numerous applications, each with its own requirements, a large variety of al-loys have been developed over the years. Use of this website signifies your agreement to our Terms of Use. 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. as well as subscriptions and other promotional notifications. Fixturing. D Type (D-Grades) This is a high carbon, high chromium (air hardening) tool steel. It is safer in hardening and has less distortion in heat-treating than the oil-hardening types. A cost-benefit analysis should be undertaken to ensure that the tool steel material chosen will provide the performance required. Receive monthly updates from IMS! This is essentially the weakest tool steel grade, and is commonly used for cold heading, cutting tools, knives, embossing, and cutlery. Selecting metal alloys requires an analysis of the desired specifications. A2 has long been known as the classic standby for a fixed blade steel. Their suitability comes from their distinctive hardness, resistance to abrasion and deformation and their ability to hold a cutting edge at elevated temperatures. Cold Work. Carbon tool steel for small production to be quenched in oil. A2 – A medium-alloy, air-hardening tool steel. Compare grades using mechanical properties including abrasion resistance, toughness, size stability, machinability and grindability. They exhibit good hardness, abrasion resistance, and deformation resistance. Ferro Tic® Properties Tables. Known for their distinct hardness, tool steels are used to make cutting tools including knives and drills, as well as to create dies that stamp and form sheet metal. Some are magnetic, some are nonmagnetic. A variety of hot working steels can maintain a sharp cutting edge at much higher temperatures of up to 1000°C. 1-877-290-5578 Notify me about educational white papers. The following list describes each of Kennametal’s categories, along with some basic guidelines on cutting tool selection: Steel: P1 – P6 . Tool steels are only as good as the heat treat they receive. ACCESS Tool steel is known for its extreme hardness, as well as it abrasion resistance and ability to hold a cutting edge at high temps. D-2: High carbon and high chrome. The AISI - SAE general purpose grades of tool steel are O-1, A-2, and D-2. The properties tables below provide technical data for many of the existing grades of Ferro-TiC®. 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. Vacuum quenched and air quenched steel. A2 – A medium-alloy, air-hardening tool steel. With so many tool steel grades available, how do you chose the correct tool steel grade for your application and what tool steel properties are required for your tool to be successful? These properties differ based on the metal or alloy composition. In selecting cold work tool steels, the metallurgical factors that ultimately affect tool performance and longevity must be considered. Tool steel selection requires more than just knowledge of the steel properties.

Air hardening (A grades): This is an all-purpose steel that’s very versatile and has a high level of chromium. It’s often used in coining, lamination, gages, chipper knives, cold shear knives, and more. 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. Though selecting a tool steel may seem straightforward, the process requires tradeoffs – making the task an art as well as a science. Other tool steel grades contain a higher percentage of different types of alloys, such as high-speed steel M2, which can be selected for high-volume production. What is Tool Steel ? UNLIMITED 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. 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. It has good machinability along with a balance of wear resistance and toughness. Tool steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools.
