N08810 Stainless Steel vs. AWS ENi-1

N08810 stainless steel belongs to the iron alloys classification, while AWS ENi-1 belongs to the nickel alloys. They have a modest 35% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is N08810 stainless steel and the bottom bar is AWS ENi-1.
