This paper overviews the current state of development of the structure and properties formation in hot rolled low alloy strip steel after its coiling. To clarify the effect of coil cooling rate on the mechanical behavior, hydrogen content, corrosion , texture and coincidence site lattice industrial experiments were made at a hot strip mill. It is revealed that the texture and CSL has a notable influence on the complex of properties: strength, ductility, toughness and corrosion resistance.

At present there is no understanding referring to the full picture of processes, that take place in the structure formation and improvement of required level of physical-mechanical properties for IF steel. That is why this paper is devoted to investigations of the texture and the quantity of the special grain boundaries to enable IF steel to high drawability.
