Hot stamping of ultra-high strength steel parts
CIRP Annals - Manufacturing Technology, 2017Abstract The demand for new processes to produce high strength parts, under appropriate cost and productivity, has grown with weight reduction and crash safety improvements in automobile design. The hot stamping processes of quenchable steel sheets potentially offer not only small forming load and high formability, but also high strength and no ...

, 2020 Materials used in car body must fulfill several performance requirements during manufacturing and service life. Reducing car weight also reduces fuel consumption and causes lower gas emissions. One way to make that possible is to use hot-stamped boron steel components because the high strength of steel sheet thickness can be reduced without losing ...

Anticorrosion mechanisms of aluminized steel for hot stamping
Surface and Coatings Technology, 2014Abstract An improved corrosion resistance of aluminized press hardened steel Usibor® AlSi compared to untreated 22MnB5 steel is observed in cyclic corrosion tests even though cracks are present in the coating after the hot stamping resulting in the simultaneous corrosion of the coating and the steel beneath.

Basic Investigations on the Hot Stamping Steel 22MnB5
Advanced Materials Research, 2005Basic research concerning the material properties of the hot stamping steel 22MnB5 has been carried out. A survey is given about the as-delivered conditions with hardness tests, micrographs and flow curves. The process window of the austenitization time, before hot stamping can take place, is defined by austenitization tests.

Properties of Tool Steels for Application in Hot Stamping
steel research international, 2019Hot stamped high‐strength steel components for car bodies become increasingly important due to the need to save weight for multiple reasons such as fuel conservation regulations. Tribological systems in tools for hot stamping depend on process parameters and may include, e.g., mechanical and thermal loads as well as adhesive and abrasive wear ...

Hydrogen embrittlement characteristics of hot-stamped 22MnB5 steel
International Journal of Hydrogen Energy, 2021Abstract Hydrogen embrittlement (HE) characteristics of 22MnB5 steel (U-bent specimen) manufactured using hot-stamping process at various temperatures were experimentally and numerically investigated. Steel resistance to HE was examined through delayed failure tests under static and cyclic loading during hydrogen charging.
