The United States is the first country to include special steel for plastic molds in tool steel, mainly represented by capital letter P. As a medium carbon Cr-Mo steel, P20 steel belongs to quenched and tempered plastic mold steel. At present, in the application of plastic molds, P20 steel is widely used as the main steel type, and it is mostly used in the pre-hardened state.
For DIN 1.2311 steel, it belongs to German steel grade. According to the German DIN 17007 digital steel number system, it is named 1.2311, which is expressed as alloy tool steel. Furthermore, 1.2311 corresponds to 40CrMnMo7 under the DIN 17006 nomenclature system.
