Abstract
A bimetallic cylinder of steel having an alloy inlay which includes chromium boride in a matrix of iron alloy containing carbon, silicon, nickel and copper. The chromium boride imparts wear resistance to the inlay and relatively high contents of chromium, nickel and silicon and the presence of molybdenum and copper in the alloy make it resistant to corrosion. The cylinder is useful for injection molding and extrusion of plastics.
