AWS E320 vs. SAE-AISI 1095 Steel

Both AWS E320 and SAE-AISI 1095 steel are iron alloys. They have a modest 38% 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 (13, in this case) are not shown.

For each property being compared, the top bar is AWS E320 and the bottom bar is SAE-AISI 1095 steel.
