Grade CW6MC Nickel vs. AWS E240
Grade CW6MC nickel belongs to the nickel alloys classification, while AWS E240 belongs to the iron alloys. They have a modest 27% of their average alloy composition in common, which, by itself, doesn't mean much. There are 22 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 AWS E240.
