Nickel 693 vs. ASTM Grade HG10 MNN Steel

Nickel 693 belongs to the nickel alloys classification, while ASTM grade HG10 MNN steel belongs to the iron alloys. They have a modest 38% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is nickel 693 and the bottom bar is ASTM grade HG10 MNN steel.
