ASTM A369 Grade FP1 vs. N08028 Stainless Steel

Both ASTM A369 grade FP1 and N08028 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 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 A369 grade FP1 and the bottom bar is N08028 stainless steel.
