Adamite rolls and rings are performance steel rolls with an optimum combination of wear and fire-crack resistance. This quality has a short range of carbon content, plus varying quantities of Nickel, Chromium and Molybdenum to achieve higher hardness levels. It can be produced either by the Static Monoblock conventional method, or by the horizontal Centrifugal Cast method.
