EN 1.4659 Stainless Steel vs. Grade M30C Nickel

EN 1.4659 stainless steel belongs to the iron alloys classification, while grade M30C nickel belongs to the nickel alloys. They have a modest 26% 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 EN 1.4659 stainless steel and the bottom bar is grade M30C nickel.
