The Cr, C and B in the alloy impart excellent abrasion resistance to solids wedging and plastic fillers like glass, mica, CaCO3. The Co and Mo in the alloy enhance the sliding and galling wear resistance between the screw and the barrel. The Cr and Mo impart enhanced corrosion resistance to hydrochloric and hydrofluoric acids generated when processing PVC and PTFE.
