<p>A casting of a white cast iron alloy which includes the following alloy composition, in weight %: chromium: 12-25%; carbon: 1.5-6%; manganese: 2-7%; silicon: up to 1.5%; molybdenum: up to 2; nickel: up to 4%; microalloying elements selected from the group of titanium, zirconium, niobium, boron, vanadium, and tungsten: up to 2% of each of one or more of the elements; and iron: balance. The microstructure of the casting has 15-60 vol % eutectic carbides and primary carbides dispersed in a ferrous matrix of martensite and is at least substantially free of pearlite.</p> |
