EN 2.4879 Cast Nickel vs. SAE-AISI S7 Steel
EN 2.4879 cast nickel belongs to the nickel alloys classification, while SAE-AISI S7 steel belongs to the iron alloys. They have a modest 20% 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 (9, in this case) are not shown.
For each property being compared, the top bar is EN 2.4879 cast nickel and the bottom bar is SAE-AISI S7 steel.
