H13/1.2344 Chromium Hot-work Steel is widely used in hot and cold work tooling applications. Due to its excellent combination of high toughness and fatigue resistance, H13 is used more than any other tool steel in tooling applications such as die casting dies for zinc, white metal, aluminum and magnesium. It is also widely used for extrusion dies, trimmer dies, gripper dies, hot shear blades, casings, and other similar hot work applications.
