Nickel Alloy NiCo20Cr20MoTi-AW vs NiCo20Cr20MoTi-CD
Nickel Alloy · NiCo20Cr20MoTi temper comparison
NiCo20Cr20MoTi-AW and NiCo20Cr20MoTi-CD are two conditions of the same nickel alloy grade, NiCo20Cr20MoTi: AW (as-welded deposit) versus CD (cold drawn). 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 520 MPa (75.4 ksi) for NiCo20Cr20MoTi-AW, about 54% more; tensile strength follows at 1,050 MPa (152 ksi) vs 820 MPa (119 ksi). In exchange, NiCo20Cr20MoTi-AW is the more ductile: elongation 30% versus 15% for NiCo20Cr20MoTi-CD, and NiCo20Cr20MoTi-CD is harder (305 HB vs 200 HB). NiCo20Cr20MoTi-AW runs hotter in service (750°C vs 600°C continuous). On the shop floor, NiCo20Cr20MoTi-AW welds better (good vs fair).

NiCo20Cr20MoTi-AW vs NiCo20Cr20MoTi-CD: 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.
