Nickel 625 vs. EN 1.4612 Stainless Steel

Nickel 625 belongs to the nickel alloys classification, while EN 1.4612 stainless steel belongs to the iron alloys. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is nickel 625 and the bottom bar is EN 1.4612 stainless steel.
