Annealed S46500 Stainless Steel vs. Annealed Type 4 Magnetic Alloy

Annealed S46500 stainless steel belongs to the iron alloys classification, while annealed Type 4 magnetic alloy belongs to the nickel alloys. They have a modest 26% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is annealed S46500 stainless steel and the bottom bar is annealed Type 4 magnetic alloy.
