Stainless Steel Alloy 611-AW vs Alloy 611-CD
Stainless Steel · Alloy 611 temper comparison
Alloy 611-AW and Alloy 611-CD are two conditions of the same stainless steel grade, Alloy 611: AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. Alloy 611-CD is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 350 MPa (50.8 ksi) for Alloy 611-AW, about 60% more; tensile strength follows at 800 MPa (116 ksi) vs 640 MPa (92.8 ksi). In exchange, Alloy 611-AW is the more ductile: elongation 30% versus 25% for Alloy 611-CD, and Alloy 611-CD is harder (250 HB vs 200 HB). Alloy 611-AW runs hotter in service (750°C vs 550°C continuous).
Alloy 611-AWChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Alloy 611-CDChoose it when strength drives the design.
Alloy 611-AW vs Alloy 611-CD: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel 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 611-AW vs Alloy 611-CD — frequently asked
Is Alloy 611-CD stronger than Alloy 611-AW?
Yes. Alloy 611-CD has a typical yield strength of 560 MPa (81.2 ksi) against 350 MPa (50.8 ksi) for Alloy 611-AW — about 60% more. Tensile strength is 800 MPa (116 ksi) vs 640 MPa (92.8 ksi).
Which condition does FabDigit quote by default, AW or CD?
Annealed is the default Alloy 611 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, Alloy 611-AW or Alloy 611-CD?
Alloy 611-CD, by a small margin. Both rate poor for machinability — 33/100 against 27/100 for Alloy 611-AW.
