ASTM Grade HL Steel vs. Grade CX2M Nickel

ASTM grade HL steel belongs to the iron alloys classification, while grade CX2M nickel belongs to the nickel alloys. They have 45% of their average alloy composition in common. There are 25 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 HL steel and the bottom bar is grade CX2M nickel.
