SAE-AISI H21 Steel vs. AWS E383

Both SAE-AISI H21 steel and AWS E383 are iron alloys. They have a modest 38% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 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 SAE-AISI H21 steel and the bottom bar is AWS E383.
