N08535 Stainless Steel vs. ASTM A369 Grade FPA

Both N08535 stainless steel and ASTM A369 grade FPA are iron alloys. They have a modest 38% 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 N08535 stainless steel and the bottom bar is ASTM A369 grade FPA.
