研究了w(C)=0.39%和w(C)=0.53%的2种Cr17Mo型耐蚀塑料模具钢的组织、力学性能及耐蚀性能。实验结果表明:2种钢材经适当的淬、回火处理后,均具有较高的硬度和强度;在弱酸和氧化性酸(醋酸和硝酸)中,均具有良好的耐腐蚀性能。
The microstructure, mechanical properties and corrosion resistance of two kinds of Cr17Mo corrosion-resistant plastic mold steels with w (C) = 0.39% and w (C) = 0.53% were studied. The experimental results show that the two steels have high hardness and strength after proper quenching and tempering treatment, and good corrosion resistance in weak and oxidizing acids (acetic acid and nitric acid).
