Nickel Alloy Hastelloy C276 As Welded vs Hastelloy C276 Cold Worked
Nickel Alloy · Hastelloy C276 temper comparison
Hastelloy C276 As Welded and Hastelloy C276 Cold Worked are two conditions of the same nickel alloy grade, Hastelloy C276: As Welded (as-welded deposit) versus Cold Worked. The chemistry is identical, so every difference below comes from the condition. Hastelloy C276 Cold Worked is the stronger of the two: yield strength 800 MPa (116 ksi) against 490 MPa (71.1 ksi) for Hastelloy C276 As Welded, about 63% more; tensile strength follows at 1,030 MPa (149 ksi) vs 760 MPa (110 ksi). In exchange, Hastelloy C276 As Welded is the more ductile: elongation 40% versus 25% for Hastelloy C276 Cold Worked, and Hastelloy C276 Cold Worked is harder (290 HB vs 192 HB). On the shop floor, Hastelloy C276 As Welded welds better (excellent vs very good).

Hastelloy C276 Cold WorkedChoose it when strength drives the design.
Hastelloy C276 As Welded vs Hastelloy C276 Cold Worked: 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 C276 As Welded vs Hastelloy C276 Cold Worked — frequently asked
Is Hastelloy C276 Cold Worked stronger than Hastelloy C276 As Welded?
Yes. Hastelloy C276 Cold Worked has a typical yield strength of 800 MPa (116 ksi) against 490 MPa (71.1 ksi) for Hastelloy C276 As Welded — about 63% more. Tensile strength is 1,030 MPa (149 ksi) vs 760 MPa (110 ksi).
Which condition does FabDigit quote by default, As Welded or Cold Worked?
Solution Annealed is the default Hastelloy C276 condition in the FabDigit quote flow (neither As Welded nor Cold Worked). 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 C276 As Welded or Hastelloy C276 Cold Worked?
Hastelloy C276 Cold Worked, by a small margin. Both rate poor for machinability — 22/100 against 15/100 for Hastelloy C276 As Welded; for welding the order is Hastelloy C276 As Welded first (excellent, 85/100) then Hastelloy C276 Cold Worked (very good, 75/100).
