EN 1.4980 Stainless Steel vs. AWS BVAu-7

EN 1.4980 stainless steel belongs to the iron alloys classification, while AWS BVAu-7 belongs to the otherwise unclassified metals. They have a modest 25% of their average alloy composition in common, which, by itself, doesn't mean much. There are 15 material properties with values for both materials. Properties with values for just one material (19, in this case) are not shown.

For each property being compared, the top bar is EN 1.4980 stainless steel and the bottom bar is AWS BVAu-7.
