R30556 Alloy vs. SAE-AISI P20 Steel

Both R30556 alloy and SAE-AISI P20 steel are iron alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is R30556 alloy and the bottom bar is SAE-AISI P20 steel.
