ABSTRACT
The materials used for die casting dies are mild steel alloys, cold or hot rolled, that are either air, oil, or water hardened. These materials contain 0.3-0.4% carbon as well as chromium, molybdenum, and vanadium as major alloying elements. A most challenging application is in the production of aluminum die castings since over 70% of all die castings are from this casting alloy. The reference here is to the inserts that are the heart of each die. The bill of materials for each die design should specify the type of steel and its hardness for each die component.
