The BG87 high strength steel strand wire rod for railway bridge is independently designed by Baotou Steel as well as its mechanical properties, microstructure and drawing property are studied through such means as controlled cooling process of rolling, determination of static CCT curve, tensile test and metallographic examination. The results showed that the strength and structure property of developed high carbon steel wire rod were good so that it could meet request for utilization of 2 300 MPa grade pre-stressed steel strand. Moreover, the product is applied on experimental bridge of Nachang-Jingdezhen-Huangshan high-speed railway so that a breakthrough of domestic 2 300 MPa high strength steel strand products is achieved.
