BÖHLER W320 ISODISC is a 3% chromium steel and corresponds to material number 1.2365 (32CrMoV12-28). This tool steel has good hot toughness as well as a very high hot hardness and resistance against heat-checkings. Compared to an X37CrMoV5-1 (material number 1.2343), the steel has an increased molybdenum content, which significantly increases its thermal resistance and thus makes it the ideal material in die closed- and open-doe forging. Due to the lower chromium content, reduced through-hardenability occurs which limits its applications to rather smaller tools.
