Tool Steel Applications and Grades Metal Supermarkets

Nov 21, 2014 · What Is Tool Steel? Tool steel is a type of carbon alloy steel that is well-matched for tool manufacturing, such as hand tools or machine dies. Its hardness, resistance to abrasion and ability to retain shape at increased temperatures are the key properties of this material. Tool steel is typically used in a heat treated condition which provides increased hardness. Tool Steel Chemical Composition HSS SteelThe chart below shows the typical chemical composition and hardness of our high-speed tool steels. You will find this broken down by our different grades of M2, M4, M7, M42, PM M4, PM T15, PM A11, PM M48, PM 23, PM 30 and PM 60. Click on the individual grade for a complete data sheet of each.
