The Bake Hardening Property of the China-Developed Bake Hardening Steel Sheet BH340

摘要

The results of the experiments on the relation between the BH value of the China-made BH340 steel and technical parameters in the auto production show that the steel sheet has an appropriate BH value in a wide range of the technical parameters and can meet the need in present auto production process. The comparison in the dent resistance of the steel sheet before and after baking manifests that the dent resistance is raised by 8 percent.
