S17700 Stainless Steel vs. Nickel 601
S17700 stainless steel belongs to the iron alloys classification, while nickel 601 belongs to the nickel alloys. They have a modest 40% 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 S17700 stainless steel and the bottom bar is nickel 601.
