EN 1.4104 Stainless Steel vs. Nickel 689
EN 1.4104 stainless steel belongs to the iron alloys classification, while nickel 689 belongs to the nickel alloys. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. There are 26 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.
For each property being compared, the top bar is EN 1.4104 stainless steel and the bottom bar is nickel 689.
