Adamite rolls are performance steel rolls with an optimum combination of wear and fire-crack resistance. This quality has a short range of carbon content, plus varying quantities of Nickel, Chromium and Molybdenum to achieve higher hardness levels. It can be produced either by the Static Monoblock conventional method, or by the horizontal Centrifugal Cast method.

Indefinite Chill rolls consist of fine interdendritic graphite evenly dispersed throughout the barrel of the roll. The size shape and distribution of the graphite, together with the carbide content. The addition of alloys such as Mg, Ni, Cr, and Mo changes the matrix structure from pearlitic, through bainite, to martensitic. The carbide form is altered from semi-continuous to rigid continuity, enhancing the strength, in-depth hardness and wear resistance properties.

The strength of the spheroidal graphite(SG) or nodular cast  iron is a result of a change in morphoglgy of flake graphite into  graphite spheroids. The lower surface area to volume of the spheroids increases its fracture toughness and hence reduces  crack propagation. SG iron is an excellent conductor of heat  and increases the resistance to fire-cracks by reducing the  locally induced thermal stresser. The impact resistance is also  increased to that of flake graphite iron.
