Abstract

The invention relates to a metallic semi-finished product based on iron and/or nickel and/or cobalt and containing 2 to 16% of aluminum, 12 to 30% of chromium and at least one highly reactive element X, in particular from the group consisting of the rare earth metals and/or their dispersed oxides. The characteristic feature of the invention is that metallic columnar crystals are formed at least in the surface region of the semi-finished product and columnar crystals consisting predominantly of aluminum oxide and/or chromium oxide grow out of the said metallic columnar crystals, the axes of the two types of columnar crystals being predominantly at right angles to the geometric surface of the semi-finished product.
