ABSTRACT:
An as-cast carbidic ductile iron is provided, having a pearlitic matrix with 5-50% by volume carbides and high wear resistance properties. The as-cast carbidic ductile iron is produced without an austempering heat treatment step. The as-cast carbidic ductile iron preferably includes a carbide stabilizing element and a spheroidizing agent.
