         Alloy Indefinite chilled cast iron roll is a cast iron with fine intercrystalline graphite evenly distributed
         throughout the working layer of roll barrel. The sizes, shapes and distributions of graphite and carbide
         are controlled by the chilling effect and the contents of alloy elements. The addition of alloy elements
         such as manganese, nickel, chromium and molybdenum chages the matrix microstructure from
         pearlite, bainite to martensite.
                 
         This roll has small hardness gradient in the woriking layer of roll barrel and is suitable to medium
         and finishing stands for bar, wire and section mills.
