Hot Work Tool Steels

Hot work steels are high-strength steels used in molds and tools with a temperature range of 250°C and above. In these materials, the expectation is to maintain mechanical properties at high temperatures, have high wear resistance, and ensure heat conductivity. These properties are achieved by adding chromium, molybdenum, tungsten, vanadium, nickel, and cobalt elements to the steel in appropriate proportions. However, as important as selecting the right hot work steel, proper machining, heat treatment, and usage are crucial. If one or more of these stages are neglected, problems such as cracking, breaking, and early wear in the mold may occur.

In recent years, the production of hot work steels produced by the Electro Slag Remelting (ESR) method has increased. The sulfur content settling at grain boundaries in these steels is at a minimum level, and distortion is minimal. Some hot work steels, such as 1.2343 and 1.2344 steels, are produced on a large scale using the EFS+ESR method. Additionally, there are extremely fine-grained hot work steels known as EFS steels. The structure of these steels is made extremely fine through additional processes during production, ensuring consistent mechanical properties at every point. Among the most commonly used hot work steels are 1.2343, 1.2344, 1.2365, 1.2367, WP7 V, 1.2713, and 1.2714 steels. By making the right choices and using the hot work steels you need, you can increase efficiency.
