Grade M3210 Cast Iron vs. Annealed N08020 Stainless Steel
Both grade M3210 cast iron and annealed N08020 stainless steel are iron alloys. Both are furnished in the annealed condition. They have a modest 38% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 material properties with values for both materials. Properties with values for just one material (7, 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 N08020 stainless steel.
