Nickel 601 vs. S41050 Stainless Steel

Nickel 601 belongs to the nickel alloys classification, while S41050 stainless steel belongs to the iron alloys. They have a modest 27% 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 (5, in this case) are not shown.

For each property being compared, the top bar is nickel 601 and the bottom bar is S41050 stainless steel.
