| Abstract: | Mecrostructure and mechanical properties of 20SiMnTi steel have been studied and analyzed when treated by different heat treatment process, by changing the sub-critical quenching temperatures. Heat treatment may improve the coordination between strength and ductility. The tensile strength may reach 950MPa,and the yield strength 920MPa while the elongation is 20% and fracture contraction 53.4%. |

| Keywords: | sub-critical quenching strength ductility |
