ASTM A387 Grade 22L Class 1 vs. N08024 Nickel
ASTM A387 grade 22L class 1 belongs to the iron alloys classification, while N08024 nickel belongs to the nickel alloys. They have a modest 36% 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 ASTM A387 grade 22L class 1 and the bottom bar is N08024 nickel.
