Abstract

This paper contains a comparative study of the die steel characteristics of both new technology (Osprey) and conventionally produced H13 hot worked die steel. Die-life, cost analysis, metallographic and fractographic examination were performed on 5% chrome steel H13 of Osprey dies which hot forged to a different reduction and then heat treated to a hardness of 42 RC with a case nitriding depth of 80 microns.
