Type 1 Magnetic Alloy vs. ASTM Grade HP Steel

Both Type 1 magnetic alloy and ASTM grade HP steel are iron alloys. They have 72% of their average alloy composition in common. There are 23 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is Type 1 magnetic alloy and the bottom bar is ASTM grade HP steel.
