SAE-AISI H14 Steel vs. AWS ERNiFeCr-2

SAE-AISI H14 steel belongs to the iron alloys classification, while AWS ERNiFeCr-2 belongs to the nickel alloys. They have a modest 24% 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 (2, in this case) are not shown.

For each property being compared, the top bar is SAE-AISI H14 steel and the bottom bar is AWS ERNiFeCr-2.
