自1980年开始研制WSPA耐候钢,通过批量试生产,收集了较全面的生产性试验数据。本文对武钢WSPA耐候钢产品的成分设计要求、在不同大气条件下的耐蚀特性、纵横向和与轧向呈45°方向的力学性能分布特性、可焊性、成型性等工艺性能及脆性转变温度生产实践进行简述,报导这些数据表明,WSPA耐候钢各项性能已达到国外CorTenA钢性能标准,可以满足国内各类铁道车辆的使用要求。 WSPA weathering steels have been developed since 1980 and have been tested in a large number of pilot production batches. In this paper, the compositional requirements of WSPA weathering steel products in Wuhan Iron and Steel Co., Ltd., the corrosion resistance under different atmospheric conditions, the distribution of mechanical properties in vertical and horizontal directions and at 45 ° to the rolling direction, the weldability, formability and other process properties and brittle transition Temperature production practices are briefly described, these data reported show that the WSPA weathering steel performance has reached the performance standards of CorTenA steel abroad, to meet the domestic use of various types of railway vehicles.
