Grade CW6MC Nickel vs. EN 1.4613 Stainless Steel

Grade CW6MC nickel belongs to the nickel alloys classification, while EN 1.4613 stainless steel belongs to the iron alloys. They have a modest 26% of their average alloy composition in common, which, by itself, doesn't mean much. There are 29 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is grade CW6MC nickel and the bottom bar is EN 1.4613 stainless steel.
