AISI 418 Stainless Steel vs. AWS BNi-10

AISI 418 stainless steel belongs to the iron alloys classification, while AWS BNi-10 belongs to the nickel alloys. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. There are 19 material properties with values for both materials. Properties with values for just one material (16, in this case) are not shown.

For each property being compared, the top bar is AISI 418 stainless steel and the bottom bar is AWS BNi-10.
