N08031 Stainless Steel vs. ASTM A387 Grade 22 Steel

Both N08031 stainless steel and ASTM A387 grade 22 steel are iron alloys. They have a modest 37% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is N08031 stainless steel and the bottom bar is ASTM A387 grade 22 steel.
