• Description:
  Laboratory wear testing was conducted by the Bureau of Mines on a variety of typical wear-resistant alloys used in mining and mineral- processing equipment to establish their relative spalling and abrasion resistance. Test specimens in the form of 75-mm-diam balls were subjected to repeated impacts until they broke, spalled excessively, or received several hundred thousand impacts. Pin specimens removed from the balls were evaluated for high-load abrasive wear. The alloys included commerical forged steels, cast steels, manganese steels, and four types of white cast iron, with a range of heat treatments. The effect of hardness and microstructure on impact wear and abrasive wear are discussed. The data should help mine operators select the compositions and heat treatments that best suit service conditions. [Description provided by NIOSH]
