Film Overlay Improves Metal Wear, Abrasion Resistance


NanoSteel Co. announced commercial availability of SHS 9800 weld overlay, the newest addition to its portfolio of Super Hard Steel (SHS) products for use in extreme service environments. Nanosteel said SHS 9800 is a premium alloy solution that features an ultra-refined crystalline nanoscale microstructure, up to a thousand times finer than existing solutions, resulting in hardness ratings up to 71 HRc with exceptional resistance to severe sliding abrasion and impact. SHS 9800 excels in high wear environments such as liners for mining truck beds and bodies, loader buckets, drag line buckets and wheels, chutes, conveyors, crushers, troughs and hoppers. SHS 9800 is a steel alloy with a unique glass-forming chemistry that allows high undercooling to be achieved during welding. This results in considerable refinement of the crystalline micro-structure to a near nanosize (submicron) range. The ultra-refined microstructure allows SHS 9800 to provide vastly improved hardness that lasts significantly longer than traditional carbide remedies, maintaining maximum hardness performance of 68–71 HRc from the weld interface throughout the entire overlay in single pass applications, allowing the overlay to be fully protective throughout the volume. The micrograph shown above illustates how 68-71 HRc maximum hardness is achieved within several microns of the weld overlay interface. HRc hardness values in the micrograph were measured from a single pass SHS 9800 overlay applied to A36 steel plate substrate.
