Description

A kind of hollow stabilizer rod of automobile is with high fatigue durability tube material
Technical field
The present invention relates to a kind of tube material, particularly a kind of hollow stabilizer rod of automobile with high fatigue durability tube material, Belong to field of metal alloy technology.
Background technology
Automobile stabilizer bar is a strength member of automobile suspension system, and its effect is, when automobile turning, to reduce and shake Dynamic amplitude, mitigates vehicle side turning probability, and improve the comfortableness of seating.In recent years, in order to improve the stability and reality of automobile Now further lightweight, in automobile manufacturing process, starts to manufacture stabiliser bar with hollow tube replacement solid material.It is steady meeting Under conditions of the anti-torsion ability of fixed pole, mitigate the deadweight of stabiliser bar, improve the effective rate of utilization of material.Hollow automobile stabilizer bar Developing direction as automotive light weight technology from now on, current hollow stabilizing rod has been widely used in automobile industry.In the prior art, use 50CrVA, 60Si2Mn steel are mainly applied in the material for manufacturing solid automobile stabilizer bar, the material for manufacturing hollow automobile stabilizer bar is adopted With the seamless pipe of 35CrMo steel, using showing, the hollow stabilizing rod anti-fatigue performance of above-mentioned material manufacture is poor, easily at stress Fatigue crack is produced, service life is low, and using effect is unsatisfactory.
The content of the invention
It is an object of the invention to provide a kind of hollow stabilizer rod of automobile with high fatigue durability tube material, overcome existing The deficiency of technology.
To achieve these goals, the technical solution used in the present invention is：A kind of high fatigue durability tube material, by The component composition of following masses percentage：
C：0.32%~0.40%, Si：0.17%~0.37%, Mn：0.40%~0.70%, S：0.010%~0.030%, P： 0.07%~0.12%, Cr：1.00%~1.30%, Mo：0.25%~0.35%, B：0.0010%~0.0040%, surplus is Fe.
What the present invention was obtained has the beneficial effect that：The tube material of the present invention is used in particular for manufacturing hollow stabilizer rod of automobile, Compared with its material cost of 50CrVA, 60Si2MnA solid stabilizing rod product reduction about 20%, weight saving rate is in 35%-45%；Than 35CrMo seamless steel pipes manufacture hollow stabilizing rod, and tensile strength improves 5%, and anti-fatigue life improves 10-20%.Intensity and tired longevity Life is significantly improved, and improves the service life of hollow stabilizer rod of automobile and the security performance of automobile.
