EN 1.4886 Stainless Steel vs. N08026 Nickel

Both EN 1.4886 stainless steel and N08026 nickel are metals with high concentrations of iron and nickel. This makes them relatively similar, despite formally belonging to different alloy families. They have 85% of their average alloy composition in common. There are 31 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is EN 1.4886 stainless steel and the bottom bar is N08026 nickel.
