摘要:
The present invention relates to a die-casting die, having a composition consisting of, in mass %: 0.16≤C≤0.26, 0.001≤Si≤0.80, 1.20≤Mn≤2.00, 2.41≤Cr≤2.73, 0.48≤Mo≤0.97, 0.003≤V≤0.28, 0.0005≤Al≤0.15, 0.0002≤N≤0.050, with the balance being Fe and unavoidable impurities, and having a hardness of 26 to 43 HRC and a thermal conductivity λ [W/m/K] measured by using a laser flash method at 25°C being 27.0≤ λ.
