Segregating by size and material type. 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. Call Today! Before discussing specific grades, it will be useful to discuss generally the properties of tool materials. Individual alloys within a grade are given a number; for example: A2, O1, etc. Carbon is by far the most important of the elements and is very closely controlled. 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. Grade Description; A-2: Air-hardening steel. A2 – A medium-alloy, air-hardening tool steel. Tool steel selection requires more than just knowledge of the steel properties. This is the most common group of metals used in engineering today. Tool steel comparison chart, compare difference maker and standard. Expands Selection, Services with New Irvine Location, September, 2010, Industrial Metal Supply Company Launches its First Retail Storefront Facility in Irvine, April, 2009, IMS Celebrates 60 years of Customer Service, As Customer Base Grows, IMS Gets Larger Cut of Metal Supply Biz, IMS Launches 3D Laser Cutter, August, 2008, Characteristics of available tool steel grades, The history of failures in similar applications. It is safer in hardening and has less distortion in heat-treating than the oil-hardening types. Along with many different applications, there are also many different tool steel grades available, including cold-working tool steels that encompass water-hardening tool steels, oil-hardening tool steels, and air-hardening tool steels. Notify me about educational white papers. A2. Tool steel is known for its extreme hardness, as well as it abrasion resistance and ability to hold a cutting edge at high temps. The higher carbon and chromium levels in D-2 steel make it a good choice for applications requiring a longer tool life. Mould steel selection – General recommendations 23 – Special recommendations 24 Selecting a tool steel supplier is a key decision for all parties, including the tool maker, the tool user and the end user. Maintenance is the variable I focus on most in the steel-selection process. Cold Work. Carbon tool steel for small production to be quenched in oil. Companies affiliated with GlobalSpec can contact me when I express interest in their product or service. 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. Choosing the optimal tool steel grade will depend on many factors, including: Tool steels are available in a wide range of grades, based on their composition, the temperature range in which they were forged or rolled, and the type of hardening they have undergone. Industrial Metal Supply offers a variety of shapes and sizes of tool steel bar in O-1 and A-2 grades. Some are magnetic, some are nonmagnetic. Tool steels are wear-resistant, ferrous alloys based on iron and carbon with high levels of alloying (hardenability and property modifying) elements such as chromium, molybdenum, tungsten, and vanadium. 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. 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. The AISI-SAE general purpose grades of tool steel are O-1, A-2, and D-2. Most tool makers that build, maintain, and repair production tooling have definite opinions on what they like and don’t like in tool steels. This is metal used to cut metal. For a tool that has broken or cracked, the toughness or impact resistance of the tool steel should be increased (note that impact resistance is reduced by notches, undercuts, and sharp radii, which are common in tools and dies). With excellent strength, enduring toughness and tremendous wear resistance, this is some of the toughest steel used to make knife blades. Although specialized tool steels aren’t required for medical injection molding, certain grades of steel are more appropriate for medical injection molding than others. An error occurred while processing the form. A-2 is an air-hardening steel containing a medium amount of alloying material (chromium). The number of parts to b produced, as well as the type, thickness, and hardn… The following list describes each of Kennametal’s categories, along with some basic guidelines on cutting tool selection: Steel: P1 – P6 . 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. 1095 has long been popular among knife makers for its easy workability, high toughness, and good edge holding. Keep in mind, however, that tool steel properties are not directly related to each other, so for instance, you may need to sacrifice toughness for higher wear resistance. The properties tables below provide technical data for many of the existing grades of Ferro-TiC®. Beginning the tool steel selection process Selecting a tool steel grade for your mold is the first step to manufacturing your medical device. As a result tool steels are suited © Copyright 2021 GlobalSpec - All rights reserved. Hot Working Tool Steels. Their suitability comes from their distinctive hardness, resistance to abrasion and deformation and their ability to hold a cutting edge at elevated temperatures. GlobalSpec collects only the personal information you have entered above, your device information, and location data. Please try again in a few minutes. Use of this website signifies your agreement to our Terms of Use. Tool steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. BEST IDEAS. D-2: High carbon and high chrome. Though selecting a tool steel may seem straightforward, the process requires tradeoffs – making the task an art as well as a science. Ferro Tic® Properties Tables. It is safer in hardening and has less distortion in heat-treating than the oil-hardening types. There are a number of different grades of tool steel that differ based on the areas for which they are designed. By submitting your registration, you agree to our Privacy Policy. 2.
