S17400 Stainless Steel vs. EN 2.4663 Nickel

S17400 stainless steel belongs to the iron alloys classification, while EN 2.4663 nickel 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 (6, in this case) are not shown.

For each property being compared, the top bar is S17400 stainless steel and the bottom bar is EN 2.4663 nickel.
