Grade M30C Nickel vs. ASTM Grade HL Steel

Grade M30C nickel belongs to the nickel alloys classification, while ASTM grade HL steel belongs to the iron alloys. They have a modest 24% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is grade M30C nickel and the bottom bar is ASTM grade HL steel.
