  • Outer layer material for composite roll for rolling and composite roll for rolling
    Patent number: 10376937
    Abstract: The present invention provides an outer layer material for a composite roll for rolling, in which the strength of secondary eutectic carbides can be increased by reducing a B amount in the secondary eutectic carbides and surface roughening resistance can be improved, and a composite roll for rolling in which this outer layer material is used in an outer layer. The outer layer material for a composite roll for rolling of the present invention is an outer layer material for a composite roll for rolling containing C in an amount of 1.8 mass % or more and 2.5 mass % or less, Si in an amount of more than 0 mass % and 1.0 mass % or less, Mn in an amount of more than 0 mass % and 1.0 mass % or less, Ni in an amount of more than 0 mass % and 0.5 mass % or less, Cr in an amount of more than 3.0 mass % and 8.0 mass % or less, Mo in an amount of more than 2.0 mass % and 10.0 mass % or less, W in an amount of more than 0 mass % and 10.0 mass % or less, V in an amount of more than 0 mass % and 10.
