S31260 Stainless Steel vs. EN 2.4680 Cast Nickel

S31260 stainless steel belongs to the iron alloys classification, while EN 2.4680 cast nickel belongs to the nickel alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 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 S31260 stainless steel and the bottom bar is EN 2.4680 cast nickel.
