Abstract: A novel family of die steels is disclosed. This family of die steels is strengthened through the formation of M2C precipitates and one or two additional precipitates, wherein M is one or more of chromium (Cr), vanadium (V), molybdenum (Mo) or tungsten (W). These additional precipitates may include copper precipitates, NiAl precipitates, and Ni(Al1-xMnx) precipitates. This creates a steel having an acceptable hardness, as well as excellent thermal conductivity.
