AWS E33-31 vs. SAE-AISI H22 Steel

Both AWS E33-31 and SAE-AISI H22 steel are iron alloys. They have a modest 33% 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 AWS E33-31 and the bottom bar is SAE-AISI H22 steel.
