The results show that after solution and aging treatment SDK1’s hardness is higher than that of high-quality H13 steel and impact energy is very close to that of the H13 steel. SDK1’s hardness is higher about 8HRC than that of H13 steel after heat treatment and hold at 620℃ for 20 h. The aging hardening of SDK1 steel mainly rely on precipitates dispersed nanoscale Cu and NiAl phases, which hold at 620℃ after 20 h with small dimensional changes. This is the reason of better stable performance of SDK1. The thermal conductivity of SDK1 steel is significantly higher than that of H13 steel in the temperature range of 100-700℃. It is connected with the low-containing elements Si and Cr in the alloy component of SDK1.
