This article examines abrasion-resistant steels and hardfacing as two effective weapons at the disposal of material handlers. It points out that abrasion is probably the single most destructive form of wear in the mixing and processing of coal. Particulate matter such as quartz sand and other minerals including coal curtail in-service life of dragline buckets, chute, crusher rolls, gates and valves, exhauster fan blades, target plates, truck beds, hoppers, vibrating pans, grinding mills, piping elbows, etc. The advantages of abrasion-resistant steels and hardfacing can be obtained in the form of a composite wear plate-hardfacing on a carbon steel backup plate. It concludes that the composite wear plate represents a major innovation since its advantages include ease of handling, low cost and easy installation, minimum on-site welding time and versatility. Its use is limited only to the consumer's creativity in application.
