In 2014,Baosteel successfully completed an industrial trial for developing products of uncoated and galvanized M n-TRIP steels w ith TS of 1 000and 1 200 M Pa,respectively,the chemical composition and typical mechanical properties of w hich are show n in Tables 5 and 6.Their formability,including bendability,hole expansion ratio,forming-limit diagram(FLD);their application properties,including delayed fracture properties,dynamic tensile test,and tensile test at various temperatures;and their w eldability w ere systematically evaluated to determine the practical application potential of these steels.These steels w ere also used to make some of the parts in BCB(left rear floor side member rear),as show n in Fig.9.
