Nickel 205-CD vs Nickel 205-H
Nickel Alloy · Nickel 205 temper comparison
Nickel 205-CD and Nickel 205-H are two conditions of the same nickel alloy grade, Nickel 205: CD (cold drawn) versus H (hardened). The chemistry is identical, so every difference below comes from the condition. Nickel 205-H is the stronger of the two: yield strength 690 MPa (100 ksi) against 520 MPa (75.4 ksi) for Nickel 205-CD, about 33% more; tensile strength follows at 760 MPa (110 ksi) vs 620 MPa (89.9 ksi). In exchange, Nickel 205-CD is the more ductile: elongation 15% versus 5% for Nickel 205-H, and Nickel 205-H is harder (215 HB vs 175 HB). Nickel 205-CD runs hotter in service (300°C vs 260°C continuous).
Nickel 205-CDChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Nickel 205-HChoose it when strength drives the design.
Nickel 205-CD vs Nickel 205-H: 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.

Nickel 205-CD vs Nickel 205-H — frequently asked
Is Nickel 205-H stronger than Nickel 205-CD?
Yes. Nickel 205-H has a typical yield strength of 690 MPa (100 ksi) against 520 MPa (75.4 ksi) for Nickel 205-CD — about 33% more. Tensile strength is 760 MPa (110 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, CD or H?
ANN is the default Nickel 205 condition in the FabDigit quote flow (neither CD nor H). 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, Nickel 205-CD or Nickel 205-H?
Nickel 205-CD. Its weldability rates very good (78/100) against very good (70/100) for Nickel 205-H.
