Nickel 22 vs. EN 1.4962 Stainless Steel
Nickel 22 belongs to the nickel alloys classification, while EN 1.4962 stainless steel belongs to the iron alloys. They have a modest 37% 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 22 and the bottom bar is EN 1.4962 stainless steel.
