| Abstract: | The main chemical compositions of spring steel 38SiMnVBE are 0.37～0.42C,0.80～1.20Si,1.20~ 1.60Mn,0.08～0. 14V,0.0005～0.0035B,and the steel requires P≤0.025%,S≤0.015% and0]≤15×10-?. The strength of steel 38SiMnVBE is 1905～2020 MPa,0.2% yield strength 1715～1850 MPa,elongation 9.0%~ 11.5%,reduction of area 44%～54%, which are higher than that of DAC series spring steel and steel 60Si2CrV in present ISO and state standard. The steel 38SiMnVBE has excellent hardenability. The test and application of the steel used for high stress and properties auto leaf spring, variable section leaf spring, suspend self spring have been carried out. |
