Refractory Metal 50Cr-50Ni-Cb-AC vs 50Cr-50Ni-Cb-HIP
Refractory Metal · 50Cr-50Ni-Cb temper comparison
50Cr-50Ni-Cb-AC and 50Cr-50Ni-Cb-HIP are two conditions of the same refractory metal grade, 50Cr-50Ni-Cb: AC (spheroidize annealed) versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. 50Cr-50Ni-Cb-HIP is the stronger of the two: tensile strength 630 MPa (91.4 ksi) against 590 MPa (85.6 ksi) for 50Cr-50Ni-Cb-AC, about 7% more. 50Cr-50Ni-Cb-HIP is the more ductile: elongation 12% versus 8% for 50Cr-50Ni-Cb-AC.

50Cr-50Ni-Cb-AC vs 50Cr-50Ni-Cb-HIP: 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-AC vs 50Cr-50Ni-Cb-HIP — frequently asked
Is 50Cr-50Ni-Cb-HIP stronger than 50Cr-50Ni-Cb-AC?
Yes. 50Cr-50Ni-Cb-HIP has a typical tensile strength of 630 MPa (91.4 ksi) against 590 MPa (85.6 ksi) for 50Cr-50Ni-Cb-AC — about 7% more.
Which condition does FabDigit quote by default, AC or HIP?
AC is the default 50Cr-50Ni-Cb condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which welds better, 50Cr-50Ni-Cb-AC or 50Cr-50Ni-Cb-HIP?
50Cr-50Ni-Cb-HIP. Its weldability rates poor (30/100) against poor (25/100) for 50Cr-50Ni-Cb-AC.
