EN 1.3543 Stainless Steel vs. Nickel 725

EN 1.3543 stainless steel belongs to the iron alloys classification, while nickel 725 belongs to the nickel alloys. They have a modest 27% 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 (12, in this case) are not shown.

For each property being compared, the top bar is EN 1.3543 stainless steel and the bottom bar is nickel 725.
