Adamite rolls and rings are engineered for high-performance rolling applications, offering an excellent balance of wear resistance, toughness, and resistance to fire-cracking. This grade features a controlled carbon content combined with varying additions of Nickel, Chromium, and Molybdenum to achieve enhanced hardness and reliable mechanical performance. Products can be manufactured by both Static Monoblock conventional casting and Horizontal Centrifugal Casting methods according to different mill requirements.
