ASTM A387 Grade 12 Class 1 vs. Grade M3210 Cast Iron
Both ASTM A387 grade 12 class 1 and grade M3210 cast iron are iron alloys. Both are furnished in the annealed condition. They have a very high 96% of their average alloy composition in common. There are 28 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.
For each property being compared, the top bar is ASTM A387 grade 12 class 1 and the bottom bar is grade M3210 cast iron.
