Hot Stamping Die Steel

Hot Stamping Die Steel

Daido Steel's tool steels lineup for hot stamping dies includes H13 and other special grades that can provide excellent high-temperature strength, softening resistance and thermal conductivity. High thermal conductive grades contribute to the improvement of the internal cooling efficiency.
Our products contribute to the prevention of wear, plating adhesion and other issues that may happen in hot stamping where forming and cooling happen at the same time.
