Grade CW6MC Nickel vs. EN 1.3549 Stainless Steel

Grade CW6MC nickel belongs to the nickel alloys classification, while EN 1.3549 stainless steel belongs to the iron alloys. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 24 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 grade CW6MC nickel and the bottom bar is EN 1.3549 stainless steel.
