Generally, rolls made in this grade are cast steel. In this case homogenous distribution of carbides which is obtain by solidification and appropriately distributed in the matrix 
by heat treatment.
Steel base rolls are particularly suitable for operating under heavy load condition. Good shock resistance and moderate wear properties make these rolls general selection for roughing and intermediate stands.
