Study on SH-CCT Diagram and Weldability of S890 Steel

Abstract:

Abstract. S890 steel is a Mo-Mn alloy system bainitic structual steel which is developed in recent years and its strength is more than 900MPa,this steel is the material of hydraulic support possessing high-performance in coal mine.The continuous cooling curve of S890 steel was determined,microstructure and hardness of this steel in various cooling rate were analysised in the paper.Results have shown that:S890 steel has good quenching degree and quench-hardenability,and it can get steady microstructures which is mainly bainite over a broad range of cooling rate.
