Nickel Alloy Hastelloy C-2000-AW vs Hastelloy C-2000-CD
Nickel Alloy · Hastelloy C-2000 temper comparison
Hastelloy C-2000-AW and Hastelloy C-2000-CD are two conditions of the same nickel alloy grade, Hastelloy C-2000: AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. Hastelloy C-2000-CD is the stronger of the two: yield strength 690 MPa (100 ksi) against 430 MPa (62.4 ksi) for Hastelloy C-2000-AW, about 60% more; tensile strength follows at 900 MPa (131 ksi) vs 730 MPa (106 ksi). In exchange, Hastelloy C-2000-AW is the more ductile: elongation 40% versus 25% for Hastelloy C-2000-CD, and Hastelloy C-2000-CD is harder (285 HB vs 200 HB). Hastelloy C-2000-AW runs hotter in service (650°C vs 450°C continuous).
Hastelloy C-2000-AWChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Hastelloy C-2000-CDChoose it when strength drives the design.
Hastelloy C-2000-AW vs Hastelloy C-2000-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.

Hastelloy C-2000-AW vs Hastelloy C-2000-CD — frequently asked
Is Hastelloy C-2000-CD stronger than Hastelloy C-2000-AW?
Yes. Hastelloy C-2000-CD has a typical yield strength of 690 MPa (100 ksi) against 430 MPa (62.4 ksi) for Hastelloy C-2000-AW — about 60% more. Tensile strength is 900 MPa (131 ksi) vs 730 MPa (106 ksi).
Which condition does FabDigit quote by default, AW or CD?
SA is the default Hastelloy C-2000 condition in the FabDigit quote flow (neither AW nor CD). 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 is easier to machine, Hastelloy C-2000-AW or Hastelloy C-2000-CD?
Hastelloy C-2000-CD, by a small margin. Both rate poor for machinability — 22/100 against 16/100 for Hastelloy C-2000-AW; for welding the order is Hastelloy C-2000-AW first (excellent, 85/100) then Hastelloy C-2000-CD (very good, 78/100).
