EN 1.7216 Steel vs. Nickel 825

EN 1.7216 steel belongs to the iron alloys classification, while nickel 825 belongs to the nickel alloys. They have a modest 32% 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 (3, in this case) are not shown.

For each property being compared, the top bar is EN 1.7216 steel and the bottom bar is nickel 825.
