N08135 Stainless Steel vs. Automotive Malleable Cast Iron

Both N08135 stainless steel and automotive malleable cast iron are iron alloys. They have a modest 37% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is N08135 stainless steel and the bottom bar is automotive malleable cast iron.
