EN 1.4923 Stainless Steel vs. N07750 Nickel

EN 1.4923 stainless steel belongs to the iron alloys classification, while N07750 nickel belongs to the nickel alloys. They have a modest 20% 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 (5, in this case) are not shown.

For each property being compared, the top bar is EN 1.4923 stainless steel and the bottom bar is N07750 nickel.
