  • Erosion and corrosion resistant white cast irons
    Patent number: 11873545
    Abstract: A casting of a hypereutectic white iron that, in an as-cast form of the casting, has a microstructure that includes a ferrous matrix that contains 12-20 wt. % chromium in solution in the matrix, eutectic chromium carbides dispersed in the matrix, primary chromium carbides dispersed in the matrix, and optionally secondary carbides dispersed in the matrix. The eutectic carbides are 15-25 vol. % of the casting and the primary carbides are 25-35 vol. % of the casting. When present, the secondary carbides are up to 6 vol. % of the casting.
