EN 1.4886 Stainless Steel vs. Nickel 908

Both EN 1.4886 stainless steel and nickel 908 are metals with high concentrations of iron and nickel. This makes them relatively similar, despite formally belonging to different alloy families. They have 80% of their average alloy composition in common. There are 29 material properties with values for both materials. Properties with values for just one material (4, 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 nickel 908.
