EN 1.4865 Stainless Steel vs. N09777 Nickel

Both EN 1.4865 stainless steel and N09777 nickel are metals with high concentrations of iron and nickel. This makes them relatively similar, despite formally belonging to different alloy families. They have a moderately high 93% of their average alloy composition in common. There are 26 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is EN 1.4865 stainless steel and the bottom bar is N09777 nickel.
