ASTM A182 Grade F6b vs. EN 1.4002 Stainless Steel

Both ASTM A182 grade F6b and EN 1.4002 stainless steel are iron alloys. Both are furnished in the annealed condition. They have a very high 98% of their average alloy composition in common. There are 32 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 ASTM A182 grade F6b and the bottom bar is EN 1.4002 stainless steel.
