Monel 400 vs. EN 1.4652 Stainless Steel

Monel 400 belongs to the nickel alloys classification, while EN 1.4652 stainless steel belongs to the iron alloys. They have a modest 25% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 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 Monel 400 and the bottom bar is EN 1.4652 stainless steel.
