R30556 Alloy vs. SAE-AISI 1090 Steel
Both R30556 alloy and SAE-AISI 1090 steel are iron alloys. They have a modest 30% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 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 R30556 alloy and the bottom bar is SAE-AISI 1090 steel.
