The invention is related to a process for the manufacture of a roll, in particular of a calender roll for a paper machine. In the process, the mantle of the roll is cast or cast and heat-treated and, in the next step, the roll mantle is machined. In the process, the surface layer of the cast-iron roll mantle is hardened and tempered so that, in the surface layer of the roll mantle, a temper-martensitic structure is produced. The roll mantle is then subjected to finishing machining in a manner known in the art. The invention is also related to a roll, in particular a calender roll for a paper machine, which roll is provided with a cast-iron mantle. The surface layer of the roll mantle is hardened and tempered so that the surface layer of the roll mantle is temper-martensitic.
