SAE-AISI M43 Steel vs. AWS ERNiCrCoMo-1
SAE-AISI M43 steel belongs to the iron alloys classification, while AWS ERNiCrCoMo-1 belongs to the nickel alloys. They have a modest 23% 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 (4, in this case) are not shown.
For each property being compared, the top bar is SAE-AISI M43 steel and the bottom bar is AWS ERNiCrCoMo-1.
