[0070] (Example)
[0071] After preparing the respective steel slabs having the compositional components shown in Table 1 below, these steel slabs were reheated at a temperature ranging from 1050°C to 1250°C. The reheated steel sheets are respectively subjected to hot rolling at a reduction ratio of 5% to 30% per pass to manufacture hot-rolled steel sheets. Then, after the hot-rolled steel sheets thus manufactured were air-cooled, the air-cooled hot-rolled steel sheets were subjected to heat treatment, intermediate heat treatment, and tempering under the conditions shown in Table 2 to manufacture pressure vessel steel sheets. In this case, the heat treatment time, the intermediate heat treatment time and the tempering time were kept constant: 80 minutes for steel type a, 105 minutes for steel type b, and 140 minutes for steel type c.
