These are High Carbon, alloy steel Rolls which are given special multi-stage heat-treatment in order to develop the combination of hardness, toughness and the wear resistance.

These rolls are hypo-eutectoid steel rolls alloyed with Chromium and Molybdenum. The heat treatment of these rolls envolve by tempering cycle which improves toughness and thermal shock resistance.

Alloy Definite Chill rolls are double poured to maintain the desired level of toughness and thermal in the journals and barrel axis.

Alloy Indefinite Chill rolls consist of cast iron with fine interdendritic graphite evenly dispersed throughout the barrel of the roll.

These rolls are stronger and more wear resistant than S.G. Pearlitic rolls and are capable of a higher hardness, especially in depth.
