ASTM Grade HG10 MNN Steel vs. Grade CW6MC Nickel
ASTM grade HG10 MNN steel belongs to the iron alloys classification, while grade CW6MC nickel belongs to the nickel alloys. They have a modest 36% 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 (3, in this case) are not shown.
For each property being compared, the top bar is ASTM grade HG10 MNN steel and the bottom bar is grade CW6MC nickel.
