Abstract
Composite steel roll, especially for finishing stands of a hot rolling mill or for four-high stands for thick plates, the external area of which is made of chromium molybdenum steel, characterised in that the chromium molybdenum steel of the external working area contains from 1.0 to 1.8% by weight of carbon, from 5 to 8% by weight of chromium, from 3 to 8% by weight of molybdenum, the total chromium and molybdenum content in the steel being between 8 and 15% by weight, the remainder consisting of iron and of elements which are normally present.
