Nickel Alloy Alloy 602 CA-CD vs Alloy 602 CA HR-SA
Nickel Alloy · Alloy 602 CA temper comparison
Alloy 602 CA-CD and Alloy 602 CA HR-SA are two conditions of the same nickel alloy grade, Alloy 602 CA: CD (cold drawn) versus HR-SA (hot rolled/forged and solution annealed plate and bar). The chemistry is identical, so every difference below comes from the condition. Alloy 602 CA-CD is the stronger of the two: yield strength 700 MPa (102 ksi) against 320 MPa (46.4 ksi) for Alloy 602 CA HR-SA, about 119% more; tensile strength follows at 900 MPa (131 ksi) vs 740 MPa (107 ksi). In exchange, Alloy 602 CA HR-SA is the more ductile: elongation 45% versus 20% for Alloy 602 CA-CD, and Alloy 602 CA-CD is harder (260 HB vs 180 HB). Alloy 602 CA HR-SA runs hotter in service (1,200°C vs 600°C continuous). On the shop floor, Alloy 602 CA HR-SA welds better (good vs fair).

Alloy 602 CA-CD vs Alloy 602 CA HR-SA: 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.

Alloy 602 CA-CD vs Alloy 602 CA HR-SA — frequently asked
Is Alloy 602 CA-CD stronger than Alloy 602 CA HR-SA?
Yes. Alloy 602 CA-CD has a typical yield strength of 700 MPa (102 ksi) against 320 MPa (46.4 ksi) for Alloy 602 CA HR-SA — about 119% more. Tensile strength is 900 MPa (131 ksi) vs 740 MPa (107 ksi).
Which condition does FabDigit quote by default, CD or HR-SA?
SA is the default Alloy 602 CA condition in the FabDigit quote flow (neither CD nor HR-SA). 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, Alloy 602 CA-CD or Alloy 602 CA HR-SA?
Alloy 602 CA HR-SA. Its weldability rates good (60/100) against fair (50/100) for Alloy 602 CA-CD.
