Impact property of grey cast iron produced from CO and steel moulds were determined experimentally and quantitatively in this work. The experimental data obtained were used to develop model (multiple linear regression equations) using stepwise technique, which were used to obtain calculated (numerical) values of these properties for each investigated material. Both experimental and calculated values of these properties were subjected to relevant statistical tests such as: - paired t-test, correlation coefficient, standard error, standard deviation and variance; and were found to compare favourably within the limits of experimental error. Hence, this developed model would be useful to oil and petrochemical industries, machine base manufactures, electric motor manufactures, agricultural equipment manufacturing industries and research institutes such as Naval, Air force and Aviation Research Institutes. Other sectors that can benefit from developed model are small and medium-scale foundry industries that are characterized with low capital outlay. © 2010, INSInet Publication.
