Nickel 908 vs. EN 1.4859 Stainless Steel
Both nickel 908 and EN 1.4859 stainless steel are metals with high concentrations of iron and nickel. This makes them relatively similar, despite formally belonging to different alloy families. They have 78% of their average alloy composition in common. There are 28 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 nickel 908 and the bottom bar is EN 1.4859 stainless steel.
