摘要：
Disclosed is a bead wire which has the following chemical composition: Mn: 5 to 35 at%; and Al: 5 to 20 at%, with the remainder being Fe and unavoidable impurities, and has an austenite single-phase structure as the steel texture. In the bead wire, the reduction in weight and the improvement in drawability can be achieved without reducing strength.
