EN 1.4418 Stainless Steel vs. Grade CW6M Nickel
EN 1.4418 stainless steel belongs to the iron alloys classification, while grade CW6M nickel belongs to the nickel alloys. They have a modest 25% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 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 1.4418 stainless steel and the bottom bar is grade CW6M nickel.
