S31730 Stainless Steel vs. Grade M30C Nickel

S31730 stainless steel belongs to the iron alloys classification, while grade M30C nickel belongs to the nickel 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 S31730 stainless steel and the bottom bar is grade M30C nickel.
