ASTM A369 Grade FP12 vs. EN 1.4852 Stainless Steel
Both ASTM A369 grade FP12 and EN 1.4852 stainless steel are iron alloys. They have a modest 37% of their average alloy composition in common, which, by itself, doesn't mean much. 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 ASTM A369 grade FP12 and the bottom bar is EN 1.4852 stainless steel.
