AWS E3155 vs. Grade FDCrV Steel

Both AWS E3155 and grade FDCrV steel are iron alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 21 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is AWS E3155 and the bottom bar is grade FDCrV steel.
