Study on forming properties of automotive high strength low alloy steel
The metallurgical structure inspection,the mechanical property test at ambient temperature and forming limit test for automotive HSLA steel such as HC260LA,HC340LA,HC420LA produced by Bengang Steel Plates Co.,Ltd.were carried out,and the results of the mechanical property test and the forming test were imported into AUTOFORM simulation software to simulate stamping process.The results showed that the mechanical properties and the forming properties of the automotive HSLA steel produced by Bengang Steel Plates Co.,Ltd.were good.The work hardening exponent n value was greater than or equal to 0.11,the plastic strain ratio r value was about 1.0,the elongation Ag was greater than or equal to 12 ％ and the ultimate strain FLD0 under the plane strain state was greater than 20 ％,which met the requirements of producing the automotive structure parts such as longitudinal beam.
