在过去的几十年里，品种结构调整一直是中国钢铁工业的重要任务。伴随中国钢铁产量的快速增长，在高强度低合金钢（HSLA）技术领域取得了一系列研究成果，并在实际品种开发中获得了成功的应用，如细晶/超细晶粒钢技术、微合金钢的析出相控制技术等。“十二五”期间国内外装备制造业的发展为中国钢铁工业产品结构调整带来了机遇和挑战。通过使用性能更优、用量更少的HSLA钢，可大量节约钢材消耗，减轻对资源、能源、环境的压力。毫无疑问，积极推进HSLA钢的应用是实现中国钢铁工业可持续发展的必由之路。

During the last decade, the adjustment of product segments always is a very important task of iron industry, and upgrading of steel products has being impelled actively by Chinese iron and steel industry. With rapidly increasing of iron and steel production, a series of research achievements have been made in the technology area of high strength low alloy(HSLA) steel, and also have been applied successfully in the actual production, e.g. the technology of fine grain and ultra-fine grain steels, the technology for the control of microalloying precipitates. It is an important strategic goal of “Twelfth Five-Year Plan” for Chinese iron and steel industry that the adjustment of steel product segments and meeting the requirements for upgrading of domestic and oversea equipment manufactory industry. Adopting HSLA steel with better performance, instead of plain steel, could save steel consumption largely, and also release pressures from resource, energy and environment. Without doubt, it is the only way to realize the sustained development of Chinese iron and steel industry by popularizing the application of HSLA steels vigorously.
