Grade M3210 Cast Iron vs. Annealed ASTM B522 Class II

Grade M3210 cast iron belongs to the iron alloys classification, while annealed ASTM B522 class II belongs to the otherwise unclassified metals. There are 21 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is grade M3210 cast iron and the bottom bar is annealed ASTM B522 class II.
