These rolls are hypo-eutectoid steel rolls alloyed with Chromium and Molybdenum. The heat treatment of these rolls involves normal double annealing followed by tempering cycle which improves toughness and thermal shock resistance. The microstructure is promarily pearlitic with broken cementite. These types of Rolls offer mechanical strength of higher degree with good weldability.

Application: These rolls are ideally made for Blooming mills and Roughing Stands for Light and Heavy Section Mills.
