EN 1.4874 Stainless Steel vs. SAE-AISI S5 Steel

Both EN 1.4874 stainless steel and SAE-AISI S5 steel are iron alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is EN 1.4874 stainless steel and the bottom bar is SAE-AISI S5 steel.
