Nickel 30 vs. S17400 Stainless Steel

Nickel 30 belongs to the nickel alloys classification, while S17400 stainless steel belongs to the iron alloys. They have a modest 37% 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 (6, in this case) are not shown.

For each property being compared, the top bar is nickel 30 and the bottom bar is S17400 stainless steel.
