S35135 Stainless Steel vs. SAE-AISI 4037 Steel

Both S35135 stainless steel and SAE-AISI 4037 steel are iron alloys. Both are furnished in the annealed condition. They have a modest 38% 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 S35135 stainless steel and the bottom bar is SAE-AISI 4037 steel.
