EN 1.4849 Stainless Steel vs. Monel K-500

EN 1.4849 stainless steel belongs to the iron alloys classification, while Monel K-500 belongs to the nickel alloys. They have a modest 40% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is EN 1.4849 stainless steel and the bottom bar is Monel K-500.
