... important advantage of cast steel, particularly the plain carbon grade, is its weldability. It can be rewelded with steel or hardfaced with tool steel, aluminum bronze, or other wear-resistant hardfacing alloy. Because of its resistance to galling, it is less desirable for dies used for forming carbon and...
