Analysis and Countermeasures of Common Defects in Ductile Iron Castings

Ductile iron is an important casting metal material developed in recent 40 years in China. The tensile strength, plasticity and toughness of nodular cast iron are higher than those of other cast iron due to the small stress concentration caused by spherical graphite and the small splitting effect on the matrix. Compared with steel with … Continue reading Analysis and Countermeasures of Common Defects in Ductile Iron Castings
