Zusammenfassung:	Process for treating a body of steel to promote its adherence to a composition which includes at least a rubber, containing the following points: a body at least the surface of which is of stainless steel is used, this steel containing at least 0.02% and at most 0.2% carbon, at least 3% and at most 20% nickel, at least 12% and at most 28% chromium, the sum of the nickel and the chromium being at least equal to 20% and at most equal to 35%, all of these percentage values being by weight; the structure of the steel includes at least 20% by volume of martensite and is without austenite or it comprises less than 80% thereof by volume; the surface of the body is activated and then treated with at least one starting silane so that it is covered with a film constituted only, or substantially only, of one or more silanes, in such a manner that this surface treated in this way can be placed directly in contact with the composition. Articles comprising a rubber composition and a metal body which has been treated in accordance with the process of the invention, such articles being for instance tires.
