BEAD WIRE HAVING LIGHT WEIGHT AND EXCELLENT DRAWABILITY, METHOD FOR PRODUCTION OF THE BEAD WIRE, AND LIGHTWEIGHT TIRE
Document Type and Number:
WIPO Patent Application WO/2007/129501
Kind Code:
A1
Abstract:
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.
