Monel 400 vs. AISI 310 Stainless Steel
Monel 400 belongs to the nickel alloys classification, while AISI 310 stainless steel belongs to the iron alloys. They have a modest 23% of their average alloy composition in common, which, by itself, doesn't mean much. There are 30 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 Monel 400 and the bottom bar is AISI 310 stainless steel.
