1. ESR steel is a hot work tool steel with a chromium-molybdenum-vanadium alloy, offering high mechanical strength, good toughness, ductility, as well as excellent machinability and polishability. This high-grade material has undergone an electro-slag remelting (ESR) process and special thermo-mechanical treatment to refine it, resulting in high levels of toughness and, consequently, thermal fatigue resistance. The use of 1. ESR quality material in molds ensures longer mold lifetimes.
