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.

Thermomechanical rolled plates of structural steels having low carbon equivalent, and thus an excellent weldability. They are used for more demanding steel structures and their supporting elements. The impact energy is guaranteed also at temperature -50 °C which facilitates a wide range for their usage.

Používají se na strojní součásti ve všech oblastech strojírenské výroby. Ve většině případů jsou obtížně svařitelné. Jsou dodávány ve stavu žíhaném na měkko (+A) nebo normalizovaném (+N) podle následující tabulky. Výrobky z plechů se dále zpracovávají tzv. zušlechťováním (obvykle kalení a popouštění), teprve po něm získávají své typické vlastnosti, tj. vysokou houževnatost, tvrdost a pevnost.

These steels feature guaranteed fine grain structure and low carbon equivalent. Mechanical properties of these plates are guaranteed at high temperatures (up to 400 °C) – yield strength R_p0,2 as well as at low temperatures (down to -50 °C) – impact energy KV; therefore, they can be used for constructions of more demanding pressure vessels working under high as well as low temperatures.

These steels feature guaranteed fi ne-grain structure and low carbon equivalent. Mechanical properties of these plates are guaranteed at
high temperatures (up to 400 °C) – yield strength Rp0,2 as well as at low temperatures (down to -50 °C) – impact energy KV; therefore,
they can be used for constructions of more demanding pressure vessels working under high as well as low temperatures.

Thermomechanical rolled plates having higher min. yield strength up to 460 MPa are designed for pressure vessels and facilities working under normal or low temperatures. These plates have excellent weldability because of low carbon equivalent. Impact energy is guaranteed even at temperature -50 °C.
