Grade M3210 Cast Iron vs. Annealed SAE-AISI H41

Both grade M3210 cast iron and annealed SAE-AISI H41 are iron alloys. Both are furnished in the annealed condition. They have 85% of their average alloy composition in common. There are 22 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 SAE-AISI H41.
