Alloy Steel Base Adamite Rolls are hyper-eutectoid steel alloyed with Nickel, Chromium, and Molybdenum, featuring a higher Carbon content ranging from 0.80% to 2.00%. Vanadium is also added to achieve the desired microstructure. These rolls exhibit higher mechanical strength and thermal/wear resistance. The rolls undergo a multi-stage, high-temperature heat treatment cycle, including Normalizing/Hardening followed by a tempering cycle. This imparts a combination of hardness, toughness, and wear resistance required for a specific application. The microstructure consists of a fine pearlitic matrix with spheroidized carbide.
