Nickel 685 vs. EN 1.4962 Stainless Steel

Nickel 685 belongs to the nickel alloys classification, while EN 1.4962 stainless steel belongs to the iron alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 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 nickel 685 and the bottom bar is EN 1.4962 stainless steel.
