This investigation was conducted to determine whether there are correlations between CVN, HRc and K Ic test results at room temperature for AISI H11/H13 hot‐work tool steels that could be developed to a tool for materials engineers and the structural designers. The results showed that such correlations do exist for electro‐slag‐remelted (ESR) and conventional AISI H11 hot‐work tool steel. Static K Ic values were correlated with the results of standard CVN impact tests and the obtained hardness values at room temperature. Furthermore, the results show that the correlation can also be used to calculate K Ic values from standard CVN impact tests and the respective Rockwell‐C hardness for AISI H13 tool steel. In general, the results of this investigation show that the correlation between the values for K Ic , CVN and HRc can be used to estimate the K Ic values from the CVN test results and the Rockwell‐C hardness.
