Type 3 Magnetic Alloy vs. AWS E316

Type 3 magnetic alloy belongs to the nickel alloys classification, while AWS E316 belongs to the iron alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 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 3 magnetic alloy and the bottom bar is AWS E316.
