Abstract：More and more efforts have been paid on the research and development of steel products, resulting in expansion of steel category and steel grade. 50 year history has made Institute for Structural Materials of CISRI high reputation in the research and development of steel grades. The paper will review the recent progress in the research activities on steel products, including plain low carbon steel, high strength loaw alloy steel, alloy structure steel, ultrahigh strength steel, bearing steel, stainless steel and corrosion resistance alloy, heat resistance steel and alloy, tool steel and mould steel, and the related technologies, etc.. It is believed that the new steel grades have been invented and will be created continuously by the research activities on steel products. The trend for steel is to develop steel products with the characteristics of high performance, low cost, easy fabrication, low tolerance and environment benign.
