摘　　要：分析了高强度D型石墨铸铁的化学成分,对其力学性能进行了阐述,并通过机加工实验证明:在同等抗拉强度下,D型石墨铸铁的切削性能、气密性和强度均优于普通高强度的灰铸铁。The chemical composition of high-strength D-type graphite cast iron is analyzed, and its mechanical properties are described. And through machining experiments, it is proved that under the same tensile strength, the cutting performance, air tightness and strength of D-type graphite cast iron are better than ordinary high-strength gray cast iron.
