High strength steel wire for use e.g. in tire reinforcement is treated so as to have a cementite free surface region. This can be achieved by electroplating or other coating methods, or be decarburizing the surface. The wire has increased resistance to hydrogen embrittlement and corrosion fatigue. The wire with its ferrous surface region is then covered with a rubber adherent outer layer of e.g. brass. |
