EN 1.4869 Casting Alloy vs. Grade M35-1 Nickel

Both EN 1.4869 casting alloy and grade M35-1 nickel 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 EN 1.4869 casting alloy and the bottom bar is grade M35-1 nickel.
