Grade N7M Nickel vs. N08800 Stainless Steel
Grade N7M nickel belongs to the nickel alloys classification, while N08800 stainless steel belongs to the iron alloys. They have a modest 36% 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 (8, in this case) are not shown.
For each property being compared, the top bar is grade N7M nickel and the bottom bar is N08800 stainless steel.
