Alloy Cast Steel Base Adamite Rolls & Rings
Alloy Cast Steel Base Adamite Rolls are hypereutectoid steel of Pearlitic Microstructure (Pearlite + Carbides) which are produced from alloyed (Mn, Cr, Ni & Mo). These Rolls are subjected to sophisticated multi-stage high temperature Heat- Treatment by Double Annealing followed by tempering cycle to the best microstructure which is capable of a higher mechanical strength with thermal and wear resistance along with hardness in depth (Constant Hardness Curve).
