Claim 3: Gaspard et al. further discloses the forged steel roll for cold rolling wherein the chemical composition contains, by mass%, at least one selected from the group consisting of Ni: 0.05 to 1.20% (Table 1, less than 1.0), V: 0.10 to 2.00% (Table 1, 1.0-3.0), and Nb: 0.10 to 1.00% (Table 1, 0.0-0.5).
Claims 4-6: Gaspard et al. further discloses the forged steel roll for cold rolling wherein a shrinkage start temperature in a temperature elevation process is 300°C or more (see Examples 1 and 2, the shrinkage start temperature is 1400°C to 1200°C and solidification occurs at a rate of 50° C/min).
