a high chromium white cast iron (ii d astm a532-10) is commonly used to manufacture the coal grinders. as-cast alloys have excellent wear resistance after destabilization treatment. consequently the literature only provides information about as-cast material. this research objective studies the wear of annealed ii d alloy after destabilization
astm a532 class ii type d mining crushing liners chute liners crushing bars and anvils hammers and mining crusher parts . this alloy has a good corrosion resistance although for a more extreme corrosion environment and abrasive wear mechanism consider using an alloy with 28 to 30% cr.
castings poured with this alloy can be machined but not drilled or tapped. machining would be done for fit surfaces only. the increased amount of mo improves the hardenability of the alloy as well which is a benefit to thicker section castings. for further increased toughness use an astm a532 class ii type b.
