Nickel 601 vs. S15700 Stainless Steel
Nickel 601 belongs to the nickel alloys classification, while S15700 stainless steel belongs to the iron alloys. They have a modest 38% 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 nickel 601 and the bottom bar is S15700 stainless steel.
