Grade M35-2 Nickel vs. EN 1.4869 Casting Alloy

Both grade M35-2 nickel and EN 1.4869 casting alloy are nickel alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a modest 38% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 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 grade M35-2 nickel and the bottom bar is EN 1.4869 casting alloy.
