AWS BVAg-18 vs. AWS BAg-9

Both AWS BVAg-18 and AWS BAg-9 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 80% of their average alloy composition in common. There are 17 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is AWS BVAg-18 and the bottom bar is AWS BAg-9.
