# Grade M30C (J24130) Cast Nickel

Grade M30C nickel is a nickel alloy formulated for casting. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. M30C is the ASTM designation for this material. J24130 is the UNS number.

The graph bars on the material properties cards below compare grade M30C nickel to: cast nickels (top), all nickel alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
