Austenitic cast iron can have hardnesses similar to nonalloyed but may show better resistance due the increased inherent of compared . It can also be alloyed for improvement of corrosion resistance and strength. Ductile and gray cast irons show about equal resistance to alkalis but susceptible cracking highly alkaline solutions while not. Neither cast iron structure nor graphite morphology has an important influence corrosion of soils. Few other additions are made to cast iron which has substantial effect corrosion resistance

These cast irons show good resistance in oxidizing and reducing atmospheres are not affected significantly by concentration or temperature. Chromate coatings are sometimes used as supplement to Cd plating order prevent the formation of powdery corrosion products. These are i white cast iron where is present FeC ii malleable which has irregularly shaped nodules of graphite iii gray in form flakes iv ductile spherical and compacted short fat interconnected

Cr and Mo are also used in combination with Si to develop corrosion resistance specific atmospheres. NiP diffusion coatings offer corrosion resistance approaching that obtainable with stainless steel. The fourth group consists of high Cr cast irons. As with Ni small addition of Cr is used to refine graphite and matrix These refinements improve corrosion resistance cast iron seawater weak acids

High Cr cast iron with content more than gives very good resistance to HNO acid especially in dilute concentrations. Other environments Nonalloyed cast is used melting crucible for such low metals Pb zinc Zn Cadmium Cd magnesium Mg and aluminum . Therefore in some of uses corrosion rates may be comparatively high first few hours even days exposure then decline to extremely low steady state remaining time cast iron is exposed corrosive environment
