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.

EQUIVALENT DESIGNATION

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.

EQUIVALENT DESIGNATION

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.
