Abstract: Hot-stamping is one of the most important processes for manufacturing ultra-high-strength components. Particularly in automotive chassis construction, hot-stamped components are very popular for meeting lightweight requirements because of to their good strength-to-weight ratio. Due to legal regulations, lightweight efforts are also increasing in the area of heavy-duty vehicles, opening up potential for the use of hot-stamped components as well. Up to now, fine-grain structural steels with sheet thicknesses of up to 9.0 mm were the main materials used. The substitution of these sheets with thinner, hot-stamped components offers great lightweight potential and is therefore being researched. In order for the hot-stamped components to be used in this area, they must meet special requirements. As a result of the long service life, particular focus is therefore placed on fatigue strength. For this reason, the conventional process route of hot-stamping was optimized in this work so that hot-stamped thick sheets of the manganese-boron-steel 22MnB5 with improved fatigue strength properties can be produced economically. Therefore, conventional furnace heating was substituted by resistance heating. In addition, the influence of sandblasting as a post-treatment was investigated.
