AISI 334 Stainless Steel vs. AWS ENi-1

AISI 334 stainless steel belongs to the iron alloys classification, while AWS ENi-1 belongs to the nickel alloys. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.

For each property being compared, the top bar is AISI 334 stainless steel and the bottom bar is AWS ENi-1.
