AWS E3155 vs. SAE-AISI H41 Steel

Both AWS E3155 and SAE-AISI H41 steel are iron alloys. They have a modest 39% 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 AWS E3155 and the bottom bar is SAE-AISI H41 steel.
