Grade M30H Nickel vs. Grade CZ100 Nickel

Both grade M30H nickel and grade CZ100 nickel are nickel alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 68% of their average alloy composition in common.

For each property being compared, the top bar is grade M30H nickel and the bottom bar is grade CZ100 nickel.
