Summary:

In order to attain the gauge reduction of outer body panels without spoiling the dent-resistance and formability, a bake-hardenable Al-killed steel sheet, named RBH-35, and has been developed in the conventional box-annealing process. RBH-35 is an 0.01% carbon, low manganese and rephosphorized Al-killed steel sheet retaining solute carbon of about 10 ppm. The steel exhibits high r-value, bake-hardenability of 40 MPa, ultimate tensile strength of above 350 MPa and substantially non-aging property. Results of stamping test of door outer panel showed that RBH-35 is the most suitable steel sheet for the thinning of outer body panels by about 10%. This paper reports the metallurgical features, mechanical properties and applications of the steel
