AWS BAg-21 vs. AWS BAg-10

Both AWS BAg-21 and AWS BAg-10 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 83% of their average alloy composition in common. There are 16 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 BAg-21 and the bottom bar is AWS BAg-10.
