LIGHTWEIGHT WIRE FOR BEAD HAVING EXCELLENT DUCTILITY, ITS PRODUCTION METHOD AND LIGHTWEIGHT TIRE

摘要

PROBLEM TO BE SOLVED: To provide a wire for a bead in which lightening in weight and the increase of ductility are made possible without deteriorating its strength. SOLUTION: The wire for a bead has a composition comprising, by atom, 5 to 35% Mn and 5 to 20% Al, and the balance Fe with inevitable impurities, and has a steel structure composed of an austenite single phase structure.
