宝钢为火车提速研制开发了多种铁路专用钢种。有的提高性能、降低成本,有的替代进口。 宝钢早就瞄准铁路提速而形成的新的市场空间,1996年起就进行车轴钢的升级研制。他们开发的50车轴钢坯在保持塑性、韧性的同时,大大提高了疲劳强度。其使用寿命较前代产品提高一倍以上,达到15年,适应了火车提速需求。现年供货量为4万余t,占国内市场70％的份额。今年,宝钢50车轴钢坯享受上海免税政策。 Baosteel developed a variety of special steel grades for speeding up of trains. Some improve performance, reduce costs, and some alternative imports. Baosteel has long aiming at the new market space formed by the speeding up of the railway. Since 1996, it has developed the axle steel upgrade. They developed a 50-axle billet while maintaining ductility, toughness, while greatly improving the fatigue strength. Its service life more than doubled over the previous generation, reaching 15 years, to adapt to the train speed requirements. The current supply of 40,000 t, accounting for 70% of the domestic market share. This year, Baosteel 50 axle billet enjoy the tax-free policy in Shanghai.
