AISI 440C Stainless Steel vs. AWS ENiCrMo-4
AISI 440C stainless steel belongs to the iron alloys classification, while AWS ENiCrMo-4 belongs to the nickel alloys. They have a modest 22% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is AISI 440C stainless steel and the bottom bar is AWS ENiCrMo-4.
