FIELD: metallurgy.
SUBSTANCE: roll contains the following components, wt %: C 0.8-1, Mn 0.2-0.5, Si 0.2-2.0, Cr 7.0-13.0, Mo 0.6-1.6, V 1.0-3.0, rest for Fe and possible accidental admixtures. The roll microstructure includes tempered martensite with residual austenite below 5 vol %, and open net of eutectic carbides with their content below 5 vol %. The roll has Vickers hardness from 780 to 840, and internal compression stress from -300 MPa to -500 MPa.
EFFECT: improved roll surface.
