| Abstract: | An extrusion die of H13 steel was found cracked after quenching. Chemical analysis and metallographic examination were performed to reveal the cause of cracking. The results show that chromium content of the cracked die is in excess of standard value together with such defects as segregation and micro pores, causing cracking during quenching. |

| Keywords: | extrusion die segregation micro pore stress concentration |
