Cold Worked Monel K-500 vs. Work Hardened ASTM B685 Alloy
Cold worked Monel K-500 belongs to the nickel alloys classification, while work hardened ASTM B685 alloy belongs to the otherwise unclassified metals. They have a modest 30% of their average alloy composition in common, which, by itself, doesn't mean much. There are 17 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 cold worked Monel K-500 and the bottom bar is work hardened ASTM B685 alloy.
