Embodiment
[0096] Steel slabs having the chemical compositions shown in Table 1 were heated to different temperatures, and the heated slabs were hot-rolled to obtain hot-rolled steel sheets each having a thickness of 2.0 mm. During the hot-rolled steel plate manufacturing process, the heating temperature, finish rolling temperature, cooling rate and coiling temperature are changed. Samples were prepared from hot-rolled steel sheets after pickling. In order to obtain the hole expansion ratio λ that provides the standard of tensile flanging, 130mm is cut out from the steel plate 2 A steel sample of the size of , and then drill a 10mmФ hole on the sample. Then when the crack penetrates the steel plate, a 60-degree conical drill bit is pushed upward from below, and the hole diameter d is measured. The expansion ratio λ[%] can be calculated by the following formula:
[0097] λ(%)=100·(d-10) / 10
[0098]The mechanical properties of the steel plate are obtained by taking out the JIS 5 tensil...
