Nickel 686 vs. EN 1.4515 Stainless Steel

Nickel 686 belongs to the nickel alloys classification, while EN 1.4515 stainless steel belongs to the iron alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 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 nickel 686 and the bottom bar is EN 1.4515 stainless steel.
