N08020 Stainless Steel vs. ASTM A372 Grade E Steel

Both N08020 stainless steel and ASTM A372 grade E steel are iron alloys. They have a modest 39% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is N08020 stainless steel and the bottom bar is ASTM A372 grade E steel.
