SAE-AISI M4 Steel vs. EN 2.4665 Nickel
SAE-AISI M4 steel belongs to the iron alloys classification, while EN 2.4665 nickel belongs to the nickel alloys. They have a modest 29% 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 (10, in this case) are not shown.
For each property being compared, the top bar is SAE-AISI M4 steel and the bottom bar is EN 2.4665 nickel.
