Alloy Steel Base Rolls

These Rolls are alloyed with NickeL, Chromium, Mar:lganese and Molybdenum with Carbon content between 0.50% and 2.00% as well as little amount of Vanadium is also added for the improvement of better microstructure. So these are capable of a higher mechanical strength with thermal and wear resistance. These Rolls undergo a sophisticated multi-stage high temperature Heat - Treatment (Double Annealing followed by tempering cycle) to give the combination of hardness, toughness and wear resistance required for the particular application. The lower Carbon grades will have a structure consisting offerrite arid fine Pearlite which, as the Carbon content is raised, transitions to a fully Pearlitic structure and on to one containing free carbide in a matrix of fine Pearlite and even some Bainite for the highest Carbon grades. All rolls of this material are statically tangentially single poured.
