ADAMITE ROLLS
Adamite Rolls are basically alloy steel rolls (a kind of high carbon steel) having hardness ranging from 40 degrees shore c to 55 degrees shore c with carbon percentage ranging from 1.35% to 2%. These rolls are primarily supplied for initial stands, where wear resistance is important along with considerable strength and toughness.
