ASTM Grade LC4 Steel vs. EN 2.4608 Nickel

ASTM grade LC4 steel belongs to the iron alloys classification, while EN 2.4608 nickel belongs to the nickel alloys. They have a modest 23% 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 (3, in this case) are not shown.

For each property being compared, the top bar is ASTM grade LC4 steel and the bottom bar is EN 2.4608 nickel.
