ASTM A182 Grade F5 vs. N08031 Stainless Steel

Both ASTM A182 grade F5 and N08031 stainless steel are iron alloys. Both are furnished in the annealed condition. They have a modest 39% 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 (5, in this case) are not shown.

For each property being compared, the top bar is ASTM A182 grade F5 and the bottom bar is N08031 stainless steel.
