How to handle the internal stress of ductile iron, and a comprehensive overview of the effect data
Ductile iron castings, like other metal castings, naturally develop internal stresses during solidification due to uneven cooling and phase transformation. Additional stress is introduced during machining from cutting forces and clamping.If untreated, residual internal stress can release over time,
Interpretation of common defects such as shrinkage cavities, shrinkage porosity, slag inclusion, and graphite floating in cast iron components
Ductile iron, widely developed in China over the past 40 years, is a strong, tough, and cost-effective casting material. Its spherical graphite structure reduces stress concentration, giving it better tensile strength, plasticity, and toughness than other cast irons. While its plasticity is lower th
