Grade CW12MW Nickel vs. EN 1.4923 Stainless Steel
Grade CW12MW nickel belongs to the nickel alloys classification, while EN 1.4923 stainless steel belongs to the iron alloys. They have a modest 20% 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 (9, in this case) are not shown.
For each property being compared, the top bar is grade CW12MW nickel and the bottom bar is EN 1.4923 stainless steel.
