SAE-AISI 9254 Steel vs. S35135 Stainless Steel

Both SAE-AISI 9254 steel and S35135 stainless steel are iron alloys. Both are furnished in the annealed condition. They have a modest 39% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI 9254 steel and the bottom bar is S35135 stainless steel.
