S44660 Stainless Steel vs. EN 2.4642 Nickel

S44660 stainless steel belongs to the iron alloys classification, while EN 2.4642 nickel belongs to the nickel alloys. They have a modest 38% 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 S44660 stainless steel and the bottom bar is EN 2.4642 nickel.
