Also suitable for hot work tools where the operating temperature does not exceed 1000°F (538°C). Tool steels fails in different ways. Tool steel is commonly used to make tools because of its hardness, resistance to abrasion and ability to withstand high pressures. In the fifth and final part of our Types of Steel video blog series, we take an in-depth look at Tool Steel types and grades. Its hardenability is low, so W-group tool steels must be subjected to a rapid quenching, requiring the use of water. Pry bars and big old cold chisles are good tool steel (often 5160 and 1095). Our hot rolled and cold rolled steel is available in a wide range of shapes including: bars, tubes, sheets and plates. In Europe, shock steels often contain 0.5-0.6 % carbon and around 3% nickel. Modern air-hardening steels are characterized by low distortion during heat treatment because of their high-chromium content. Their suitability comes from their distinctive hardness, resistance to abrasion and deformation and their ability to hold a cutting edge at elevated temperatures. This is the MIL-SPEC alloy used for the bolt. Tool steel contains various amounts of tungsten, molybdenum, cobalt and vanadium to increase the heat resistance and durability of the metal. Also, with certain grades the manganese content is restricted in order to minimize the potential of cracking while water quenching. This type of tool steel has been designed to resist shock at low or high temperatures (E.g. Tensile Strength: 1103 MPa. There are six groups of tool steel: water-hardening, cold-work tool steels, shock-resisting, high-speed, hot-work, and special purpose/plastic mold tools steel.
