SAE-AISI 4621 Steel vs. EN 2.4889 Nickel
SAE-AISI 4621 steel belongs to the iron alloys classification, while EN 2.4889 nickel belongs to the nickel alloys. They have a modest 26% of their average alloy composition in common, which, by itself, doesn't mean much. There are 31 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.
For each property being compared, the top bar is SAE-AISI 4621 steel and the bottom bar is EN 2.4889 nickel.
