Grade M30C Nickel vs. Grade M35-1 Nickel

Both grade M30C nickel and grade M35-1 nickel are nickel alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 97% of their average alloy composition in common.

For each property being compared, the top bar is grade M30C nickel and the bottom bar is grade M35-1 nickel.
