ASTM A227 Spring Steel vs. N06985 Nickel

ASTM A227 spring steel belongs to the iron alloys classification, while N06985 nickel belongs to the nickel alloys. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is ASTM A227 spring steel and the bottom bar is N06985 nickel.
