AWS E383 vs. SAE-AISI O6 Steel

Both AWS E383 and SAE-AISI O6 steel are iron alloys. They have a modest 36% 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 (4, in this case) are not shown.

For each property being compared, the top bar is AWS E383 and the bottom bar is SAE-AISI O6 steel.
