ASTM A372 Grade E Steel vs. Type 2 Magnetic Alloy
Both ASTM A372 grade E steel and Type 2 magnetic alloy are iron alloys. They have 52% of their average alloy composition in common. There are 25 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 ASTM A372 grade E steel and the bottom bar is Type 2 magnetic alloy.
