S41045 Stainless Steel vs. EN 2.4879 Cast Nickel

S41045 stainless steel belongs to the iron alloys classification, while EN 2.4879 cast nickel belongs to the nickel alloys. They have a modest 29% 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 (7, in this case) are not shown.

For each property being compared, the top bar is S41045 stainless steel and the bottom bar is EN 2.4879 cast nickel.
