Rolled stainless steel object and manufacturing method therefor

A rolled stainless steel object,

• wherein the surface thereof has a raised and indented pattern including a random juxtaposition of at least two types of polygons, each of said polygons having at least three sides, a surface area of between 1 and 9 mm2, and a difference between its smallest and largest dimensions of between 0.5 and 3 mm, each polygon being made up of substantially parallel rectilinear scratches, each separated by ±15° relative to the mean orientation of the scratches, having a depth of from 5 to 30 μm separated by ridge lines, and the axes of which are from 0.1 to 0.3 mm from each other, each polygon of the pattern has a reference plane, said reference plane represents the orientation of the polygon in space, the scratches have flanks, and
• a Fourier transform spectral analysis of which, carried out on a square of at least 100 mm2, shows that they have an isotropy of at least 40% between the rolling direction and the sideways direction, and two adjacent preferred angular orientations of which scratches, from among the three main preferred angular orientations thereof, are spaced apart by a minimum of 20° and a maximum of 60°.
