AISI 440B Stainless Steel vs. AWS ERNiCrFe-11
AISI 440B stainless steel belongs to the iron alloys classification, while AWS ERNiCrFe-11 belongs to the nickel alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 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 AISI 440B stainless steel and the bottom bar is AWS ERNiCrFe-11.
