SAE-AISI H22 Steel vs. N08031 Stainless Steel

Both SAE-AISI H22 steel and N08031 stainless steel are iron alloys. They have a modest 36% 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 (8, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI H22 steel and the bottom bar is N08031 stainless steel.
