ALLOY CAST STEEL ROLLS

Microstructure of Alloy
cast steel rolls
Distance from surface - mm
Hardness - ShC

CHARACTERISTICS

Carbon content in Alloy Cast Steel Rolls is in the range of 0.50% to 0.80%. These hypo-eutectoid steel rolls are alloyed with Chromium and Molybdenum. The heat treatment of these rolls involves double annealing cycles followed by tempering. This helps to improve toughness and thermal shock resistance. The microstructure is primarily fine pearlitic with broken/spheroidized cementite. These rolls have high mechanical strength with good weldability.
