摘要
The resistance to cracking corrosion of steel elongate elements, such as wires or armorings of flexible pipes or cables destined to be exposed to the corrosion of aqueous corrosive media, is increased by subjecting said elements to a series of alternate flexions in opposite directions, by passing them between rollers in staggered arrangement, so as to generate in said elements compression zones extending from each of the main external surfaces thereof to the inside over at least one third of the distance of said surface to the longitudinal axis of the element.
