Nickel 617 vs. EN 1.4415 Stainless Steel

Nickel 617 belongs to the nickel alloys classification, while EN 1.4415 stainless steel belongs to the iron alloys. They have a modest 22% 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 (3, in this case) are not shown.

For each property being compared, the top bar is nickel 617 and the bottom bar is EN 1.4415 stainless steel.
