ASTM A356 Grade 9 vs. EN 1.4874 Stainless Steel

Both ASTM A356 grade 9 and EN 1.4874 stainless steel are iron alloys. They have a modest 34% 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 (4, in this case) are not shown.

For each property being compared, the top bar is ASTM A356 grade 9 and the bottom bar is EN 1.4874 stainless steel.
