Abrasive wear is a principal cost in mining and mineral processing operations. High chromium white cast iron (WCI) further reinforced with niobium carbide (NbC) shows promise to increase component wear lives. This work investigates the effect of niobium macro-additions on microstructure. hardness and high-stress abrasive wear behaviour of Nb-containing high-Cr WCIs. https://steedaes.shop/product-category/water-sports-harnesses/
