SAE-AISI 9260 Steel vs. EN 1.4874 Stainless Steel

Both SAE-AISI 9260 steel and EN 1.4874 stainless steel are iron alloys. They have a modest 33% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI 9260 steel and the bottom bar is EN 1.4874 stainless steel.
