Type 2 Magnetic Alloy vs. ASTM A372 Grade H Steel

Both Type 2 magnetic alloy and ASTM A372 grade H steel 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 Type 2 magnetic alloy and the bottom bar is ASTM A372 grade H steel.
