Grade M3210 Cast Iron vs. Annealed ASTM B685 Alloy

Grade M3210 cast iron belongs to the iron alloys classification, while annealed ASTM B685 alloy belongs to the otherwise unclassified metals. There are 18 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is grade M3210 cast iron and the bottom bar is annealed ASTM B685 alloy.
