Grade CY40 Nickel vs. Grade M35-1 Nickel
Both grade CY40 nickel and grade M35-1 nickel are nickel alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 70% of their average alloy composition in common.
For each property being compared, the top bar is grade CY40 nickel and the bottom bar is grade M35-1 nickel.
