Type 3 Magnetic Alloy vs. S46500 Stainless Steel

Type 3 magnetic alloy belongs to the nickel alloys classification, while S46500 stainless steel belongs to the iron alloys. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. 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 3 magnetic alloy and the bottom bar is S46500 stainless steel.
