SAE-AISI F2 Steel vs. S35135 Stainless Steel

Both SAE-AISI F2 steel and S35135 stainless steel are iron alloys. They have a modest 38% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI F2 steel and the bottom bar is S35135 stainless steel.
