Nickel 690 vs. EN 1.4662 Stainless Steel

Nickel 690 belongs to the nickel alloys classification, while EN 1.4662 stainless steel belongs to the iron alloys. They have a modest 38% 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 690 and the bottom bar is EN 1.4662 stainless steel.
