AISI 422 Stainless Steel vs. EN 2.4879 Cast Nickel
AISI 422 stainless steel belongs to the iron alloys classification, while EN 2.4879 cast nickel belongs to the nickel alloys. They have a modest 30% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.
For each property being compared, the top bar is AISI 422 stainless steel and the bottom bar is EN 2.4879 cast nickel.
