AWS BVAg-29 vs. ASTM B685 Alloy

Both AWS BVAg-29 and ASTM B685 alloy are otherwise unclassified metals. They have a modest 24% 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 (3, in this case) are not shown.

For each property being compared, the top bar is AWS BVAg-29 and the bottom bar is ASTM B685 alloy.
