AWS E3155 vs. ASTM A369 Grade FP5

Both AWS E3155 and ASTM A369 grade FP5 are iron alloys. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is AWS E3155 and the bottom bar is ASTM A369 grade FP5.
