AWS E33-31 vs. ASTM A356 Grade 10

Both AWS E33-31 and ASTM A356 grade 10 are iron alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 21 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is AWS E33-31 and the bottom bar is ASTM A356 grade 10.
