S35135 Stainless Steel vs. SAE-AISI O1 Steel

Both S35135 stainless steel and SAE-AISI O1 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 19 material properties with values for both materials. Properties with values for just one material (13, 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 O1 steel.
