THE USE OF HIGH STRENGTH LOW ALLOY STEEL IN AUTOMOTIVE TUBING APPLICATIONS

Vehicle weight reductions have been achieved through the development and use of high strength, thin-walled tubing materials as alternatives to solid bar sections. Strength has been increased by the addition of carbon and manganese, and silicon, and by small additions of vanadium and columbium. Cold drawn tubing has the advantages of close dimensional control, relatively high mechanical properties, and very smooth surface quality. A thorough quality assurance program is followed. High strength low alloy (HSLA) tubing has been used in front bumper isolators suspension struts, and van control arms. The chemical and other properties of specific HSLA steels used for such purposes are tabulated.
