These rolls are self-possessed mainly of pearlite with some cementite in the structure. adamite rolls are strolled than cast iron rolls and harder than other steel rolls. an outstanding feature of adamite rolls in that the inner hardness is about the same as that of the surface. adamite steel rolls are classified as ordinary. these rolls are used in pre-finishing to polishing stands in structure mills where wear resistance is very important along with considerable amount of strength and toughness.

Alloyed rolls are special steels alloyed with nickel, chromium & molybdenum. which is used in breakdown, roughing & intermediate mills for finishing of heavy sections. these rolls are statically cast and undergo a three stage high temperature heat treatment comprising of annealing, normalizing & tempering rotation. the rolls are available in a wide variety of composition & properties to suit specific application. the matrix structure is pearlitic or bainitic depending on the alloy content. changing the carbide distribution obatined through control of chemical composition varies the hardness. finishing rolls for sheet, plate and strip mills. intermediate and finishing rolls for small section, bar and wire rod mills. also used as cold mill rolls for ferrous and non-ferrous sheets.
