Wear-Resistant Alloys are a class of materials specifically engineered to withstand surface degradation and material loss caused by mechanical wear. This wear can result from abrasion (scraping), erosion (impact by particles), adhesion (galling and seizing), and impact. Their primary function is to extend the service life of industrial equipment, reduce downtime, and improve operational efficiency in demanding environments.
