STEEL SHEET WITH HIGH CONTENT OF ALUMINIUM AND METHOD OF ITS MANUFACTURING Russian patent published in 2009 - IPC C21D9/46 C21D8/02 C22C38/06 C23C2/12 C23C2/28 B01J35/04 B32B15/01 B32B15/18 B32B15/20 B21B3/00 B23K101/02 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy field, particularly to receiving of steel sheet and foil with high content of aluminium by method of flow line production with low cost. On at least one surface of basic steel sheet, containing aluminium in amount from 3.5 up to less than 6.5 wt %, it is applied aluminium or aluminium alloy for receiving of laminated material. It is subject to cold working for giving of operating voltage and diffusive heat processing. It is received steel sheet, containing from 6.5 up to 10 wt % of aluminium, allowing texture with crystal plane aggregate α-Fe {222}, compound from 60 up to 95%, and/or planes {200}, compound from 0.01 up to 15%, relative to surface of steel sheet. Sheet is subject to additional cold rolling with receiving of foil.

EFFECT: treatability improvement, that provides receiving of products of different forms without additional operations.
