SAE-AISI 1005 Steel vs. EN 1.4887 Stainless Steel

Both SAE-AISI 1005 steel and EN 1.4887 stainless steel are iron alloys. They have a modest 40% of their average alloy composition in common, which, by itself, doesn't mean much. There are 31 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI 1005 steel and the bottom bar is EN 1.4887 stainless steel.
