EN 1.7366 Steel vs. Nickel 825

EN 1.7366 steel belongs to the iron alloys classification, while nickel 825 belongs to the nickel alloys. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 31 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 1.7366 steel and the bottom bar is nickel 825.
