Nickel Alloy NiCo20Cr20MoTi-CD vs NiCo20Cr20MoTi HR-ST
Nickel Alloy · NiCo20Cr20MoTi temper comparison
NiCo20Cr20MoTi-CD and NiCo20Cr20MoTi HR-ST are two conditions of the same nickel alloy grade, NiCo20Cr20MoTi: CD (cold drawn) versus HR-ST (hot rolled / hot forged + solution treated plate and forgings). The chemistry is identical, so every difference below comes from the condition. NiCo20Cr20MoTi-CD is the stronger of the two: yield strength 800 MPa (116 ksi) against 510 MPa (74 ksi) for NiCo20Cr20MoTi HR-ST, about 57% more; tensile strength follows at 1,050 MPa (152 ksi) vs 850 MPa (123 ksi). In exchange, NiCo20Cr20MoTi HR-ST is the more ductile: elongation 45% versus 15% for NiCo20Cr20MoTi-CD, and NiCo20Cr20MoTi-CD is harder (305 HB vs 185 HB). NiCo20Cr20MoTi HR-ST runs hotter in service (800°C vs 600°C continuous). On the shop floor, NiCo20Cr20MoTi HR-ST welds better (very good vs fair).

NiCo20Cr20MoTi-CD vs NiCo20Cr20MoTi HR-ST: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all nickel alloy 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.

NiCo20Cr20MoTi-CD vs NiCo20Cr20MoTi HR-ST — frequently asked
Is NiCo20Cr20MoTi-CD stronger than NiCo20Cr20MoTi HR-ST?
Yes. NiCo20Cr20MoTi-CD has a typical yield strength of 800 MPa (116 ksi) against 510 MPa (74 ksi) for NiCo20Cr20MoTi HR-ST — about 57% more. Tensile strength is 1,050 MPa (152 ksi) vs 850 MPa (123 ksi).
Which condition does FabDigit quote by default, CD or HR-ST?
ST is the default NiCo20Cr20MoTi condition in the FabDigit quote flow (neither CD nor HR-ST). 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, NiCo20Cr20MoTi-CD or NiCo20Cr20MoTi HR-ST?
NiCo20Cr20MoTi HR-ST. Its weldability rates very good (75/100) against fair (45/100) for NiCo20Cr20MoTi-CD.
