Abstract Only (V, Mo)C carbide remains in specimens queched from 820—870℃, the solution of it begins at 870℃ and stops at 920℃. While tempering at 400 to 700℃, the precipitates of Mo, V, Cr and Mn increase with increasing temperature and the maxinm amount of Mo, V precipitates was found at about 600℃, corresponding change of mechanical properties occurs above this temperature. However, the precipitation of Fe decreases at the temperature range of 500 to 700℃. Cr-rich M_3C was observed at 700℃.
