Abstract 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.
