ASTM Grade LC9 Steel vs. Nickel 30

ASTM grade LC9 steel belongs to the iron alloys classification, while nickel 30 belongs to the nickel alloys. They have a modest 25% 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 (5, in this case) are not shown.

For each property being compared, the top bar is ASTM grade LC9 steel and the bottom bar is nickel 30.
