EN 1.4062 Stainless Steel vs. Nickel 684
EN 1.4062 stainless steel belongs to the iron alloys classification, while nickel 684 belongs to the nickel alloys. They have a modest 22% 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 1.4062 stainless steel and the bottom bar is nickel 684.
