In this thesis, the topic of systematization of high strength steels is discussed. High-strength steels are increasingly used in the auto industry and in the manufacture of special structures that require materials that have conventional steel. High-strength steels are still developing and have undergone many stages of development, so we can raise them to these phases in generations, which is very important for the systematization of high-strength steel itself. In the thesis, the steels in general, the method of production, the properties, the alloy and the division of steel are briefly processed. Then, most of the thesis relates to high-strength steel itself. The development of high-quality steel, hardening mechanisms, and systematization according to different properties and characteristics are also dealt with. The division of high-strength steel on the generations is elaborated, and each generation and type of steel is described separately.
