Structural steels with guaranteed fine grain structure and low carbon equivalent. Because of the yield strength up to 460 MPa and impact energy guaranteed at temperature -50 °C these steels are suitable for more demanding steel structures and their supporting elements. They are suitable for construction of railway and motor vehicles, too.
