【Abstract】 This paper deals with the study on the air cooled bainitic steel. The optimum combination of strength-toughness properties of the bainite and bainite/martensite microstructure were briefly discussed. The application of these steels in industrial production may simplify the heat treating process, and the econimic profit may be markedly obtained.The brief recommendation of the novel types of air cooled bainitic steel series and their some applications in engineering were also presented.更多还原
