EN 1.4592 Stainless Steel vs. AWS ENiCrMo-4

EN 1.4592 stainless steel belongs to the iron alloys classification, while AWS ENiCrMo-4 belongs to the nickel alloys. They have a modest 26% 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 (12, in this case) are not shown.

For each property being compared, the top bar is EN 1.4592 stainless steel and the bottom bar is AWS ENiCrMo-4.
