As for normal grey iron, the chemical composition is not important comparatively. The iron foundries could adjust the compositions according to their experience as long as they could meet the physical and mechanical requirements.
Important Note:
As the material property values below are generalized figures only for quick reference and may only be applicable to certain test conditions. Thus, it is normal if you find the figures different from other reference sources that are based on a different set of test conditions.
