Grade M30C Nickel vs. EN 1.4565 Stainless Steel

Grade M30C nickel belongs to the nickel alloys classification, while EN 1.4565 stainless steel belongs to the iron alloys. They have a modest 21% 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 (4, in this case) are not shown.

For each property being compared, the top bar is grade M30C nickel and the bottom bar is EN 1.4565 stainless steel.
