ASTM Grade HF Steel vs. EN 2.4856 Nickel

ASTM grade HF steel belongs to the iron alloys classification, while EN 2.4856 nickel belongs to the nickel alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 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 HF steel and the bottom bar is EN 2.4856 nickel.
