Abstract
A roll of which surface cracks are hardly caused under the condition of repetitive heating and cooling. A roll comprises that the alloy consisting of no more than 0.10 percent by weight of carbon, 10.about.14 percent by weight of chromium, 0.1.about.1.0 percent by weight of molybdenum, 0.5.about.2.0 percent by weight of cobalt and essentially balanced iron is coated on the surface of a roll body consisting of low alloy or carbon steel by build-up welding. Therefore, build-up welding layer of the above-mentioned compositions excel in view of resistance to corrosion, and that fact is related with a long-life of a roll.
