Abstract

Abstract: Domestic made BR1500HS high-strength steel automobile door impact beam was studied by using high-frequency induction heat treatment technology, when the impact beam obtained a complete hardened microstructure under the different feeding speed between 70-120 mm/s, the relationship between heating voltage and feeding speed of the impact beam was explored. The results show that with the decrease of feeding speed, the heating voltage required for through quenching also decreases, and the demarcation line is used to distinguish whether it is completely hardened. The high-frequency induction hardening of the impact beam adopts a heating voltage range of 30 V above the dividing line, and its mechanical properties can fully meet the properties requirements of the automobile factory.

Key words: door impact beam, BR1500HS steel, microstructure, mechanical properties
