EN 1.4584 Stainless Steel vs. Monel 400

EN 1.4584 stainless steel belongs to the iron alloys classification, while Monel 400 belongs to the nickel alloys. They have a modest 30% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 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 EN 1.4584 stainless steel and the bottom bar is Monel 400.
