38SiMnVBE 弹簧钢的主要成分(%)为：0.37～0.42C

0.80～1.20Si

1.20～1.60Mn

0.08～0. 14V

0.0005～0.0035B

该钢要求P≤0.025%

S≤0.015%

[0]≤15×10-⁶ 。38SiMnVBE 钢的抗拉强度为1905~ 2020MPa

0.2%屈服强度1715～1850 MPa

延伸率9.0%～11.5%

断面收缩率44%～54%

高于现有国际和国家标准中 DAC类钢和60Si2CrVA的性能。该钢具有优良的淬透性。已在高应力、高性能汽车板簧，变截面板簧、轿车前、后悬架簧上进行试验和应用。

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% and[0]≤15×10-⁶. 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.
