EN 1.4516 Stainless Steel vs. ASTM A369 Grade FP9

Both EN 1.4516 stainless steel and ASTM A369 grade FP9 are iron alloys. Both are furnished in the annealed condition. They have a very high 96% of their average alloy composition in common. There are 31 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is EN 1.4516 stainless steel and the bottom bar is ASTM A369 grade FP9.
