Manufactured by Dörrenberg Edelstahl.
1.2343 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 1.2343 ESR quality material in molds ensures longer mold lifetimes.
1.2343 ESR (WP5) (X37CrMoV5-1) tool steel possesses a very fine-grained microstructure. The material processed through the electro-slag remelting (ESR) method provides superior results. The ESR process delays the appearance of surface cracks in the material.
