The development of a new alloy for the cylinders of injection moulding machines processing advanced reinforced polymers is described. Corrosion and wear tests produced a new composition that has comparable corrosion resistance to Hastelloy C together with wear resistance superior to currently used nickel based alloys containing a hard boride phase. The new alloy can be bonded to the interior of cylinders using a reaction sintering hipping route and has performed satisfactorily in service trials.
