Product Description

BÖHLER W303 ISODISC is a 5% chromium steel and corresponds to material number 1.2367 (X38CrMoV5-3). 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-die forging, open-die forging and extrusion.
