我国每年从各国进口数最可观的钢材及以钢为主要材料的各类技术装备。工业生产、科学研究、产品使用和教学各部门以及设计、外贸、技术引进、援外出口和国际学术交流等经常需要查明各国钢号准确的技术数据,故迫切需要一本全面收集当今世界各国钢号及其主要性能的工具书。本书勾划了世界各罔用钢概貌,综合反映了各国用钢的发展趋势,对钢材钢种的科研方向具有指导意义。
Each year, China imports the most substantial amount of steel from various countries and various types of technical equipment with steel as the main material. Often, the accurate technical data of steel grades in various countries need to be identified in industrial production, scientific research, product use and teaching departments as well as in design, foreign trade, technology import, foreign aid export and international academic exchanges. Therefore, there is an urgent need for a comprehensive collection of steel from all over the world Number and its main performance tool book. This book outlines the world’s indiscriminate use of steel profile, a comprehensive reflection of the development trend of steel in various countries, the steel research direction of steel has guiding significance.
