EN 1.8550 Steel vs. Nickel 333

EN 1.8550 steel belongs to the iron alloys classification, while nickel 333 belongs to the nickel alloys. They have a modest 21% 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 (4, in this case) are not shown.

For each property being compared, the top bar is EN 1.8550 steel and the bottom bar is nickel 333.
