SAE-AISI H42 Steel vs. AWS E33-31

Both SAE-AISI H42 steel and AWS E33-31 are iron alloys. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI H42 steel and the bottom bar is AWS E33-31.
