Grade M30C Nickel vs. AISI 334 Stainless Steel

Grade M30C nickel belongs to the nickel alloys classification, while AISI 334 stainless steel belongs to the iron alloys. They have a modest 23% 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 (9, in this case) are not shown.

For each property being compared, the top bar is grade M30C nickel and the bottom bar is AISI 334 stainless steel.
