AWS BVAg-29 vs. ASTM B522 Class I

Both AWS BVAg-29 and ASTM B522 class I are 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 (9, in this case) are not shown.

For each property being compared, the top bar is AWS BVAg-29 and the bottom bar is ASTM B522 class I.
