Grade M30H Nickel vs. N08332 Stainless Steel

Grade M30H nickel belongs to the nickel alloys classification, while N08332 stainless steel belongs to the iron alloys. They have a modest 40% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 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 grade M30H nickel and the bottom bar is N08332 stainless steel.
