Steels hardened in this way are suited for use in components subjected to high mechanical and thermal loads in downsized, energy-efficient and low-emission engines of the future. Combustion engines still have potential to save energy and reduce emissions; a current trend is to use downsized engines of the same or even increased power. Diesel injection systems have to reach higher injection pressures and improved injection accuracies in order to meet the requirements of downsizing.
