| Abstract: | The microstructures and mechanical properties of a low carbon martensite steel 0.076C 0.76Mn 0 35Si 0.64Cr 0.12V 0.03Ti 0.0044B (mass%) under water quenching condition are investigated. The results show that the properties of the steel satisfy with the requirement of the front wheel hub made of the as quenched and tempered 40Cr steel. The further improvement of mechanical properties of this steel is suggested. Meanwhile, the improtance of the automobile industrial applications of low carbon martensite steels without quenching tempering treatment is emphasized. |
