| Abstract: | The European standard of low temperature high toughness nodular iron was introduced. The influences of the microstructure,chemical composition and heat treatment on the impact toughness of nodular irons were analyzed,and based on the analysis results,a rational production process was established. The production practice proved that the properties of all kinds of castings reached requirements. |
