50Cr-50Ni-Cb vs 60Cr-40Ni: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all refractory metal grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

50Cr-50Ni-Cb vs 60Cr-40Ni — frequently asked
Is 50Cr-50Ni-Cb stronger than 60Cr-40Ni?
Yes. 50Cr-50Ni-Cb has a typical yield strength of 390 MPa (56.6 ksi) against 310 MPa (45 ksi) for 60Cr-40Ni — about 26% more. Tensile strength is 590 MPa (85.6 ksi) vs 415 MPa (60.2 ksi).
Which is cheaper, 50Cr-50Ni-Cb or 60Cr-40Ni?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, 50Cr-50Ni-Cb or 60Cr-40Ni?
50Cr-50Ni-Cb. Its weldability rates poor (25/100) against poor (20/100) for 60Cr-40Ni.
