EN 1.7366 Steel vs. EN 2.4665 Nickel

EN 1.7366 steel belongs to the iron alloys classification, while EN 2.4665 nickel belongs to the nickel 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 (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 EN 2.4665 nickel.
