Half-hard ASTM F15 vs. Half-hard Nickel 201
Half-hard ASTM F15 belongs to the iron alloys classification, while half-hard nickel 201 belongs to the nickel alloys. They have a modest 30% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 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 half-hard ASTM F15 and the bottom bar is half-hard nickel 201.
