60Cr-40Ni (R20600) Casting Alloy
60Cr-40Ni alloy is a chromium alloy. Cited properties are appropriate for the as-fabricated (no temper or treatment) condition. It has a very high heat capacity among alloys in the same category. In addition, it has a very high tensile strength and a fairly low density.
The graph bars on the material properties cards below compare 60Cr-40Ni alloy to: chromium alloys (top), all alloys in the same category (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.
