Grade CW2M Nickel vs. ASTM Grade HN Steel
Grade CW2M nickel belongs to the nickel alloys classification, while ASTM grade HN steel belongs to the iron alloys. They have 43% of their average alloy composition in common. There are 21 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.
For each property being compared, the top bar is grade CW2M nickel and the bottom bar is ASTM grade HN steel.
