Doping contributes to improve the heat resistance and enables the use of this steel the most important parts. When choosing heat-resistant steel for burdened working conditions, it is possible to change this brand to another, with lower carbon content. This instrumental steel has a relatively balanced performance of heat resistance and heat resistance, whereby so popular.
