Annealed ASTM B685 Alloy vs. Annealed Monel 400
Annealed ASTM B685 alloy belongs to the otherwise unclassified metals classification, while annealed Monel 400 belongs to the nickel alloys. They have a modest 31% of their average alloy composition in common, which, by itself, doesn't mean much. There are 19 material properties with values for both materials. Properties with values for just one material (15, in this case) are not shown.
For each property being compared, the top bar is annealed ASTM B685 alloy and the bottom bar is annealed Monel 400.
