S41050 Stainless Steel vs. Nickel 30

S41050 stainless steel belongs to the iron alloys classification, while nickel 30 belongs to the nickel alloys. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 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 S41050 stainless steel and the bottom bar is nickel 30.
