Nickel Alloy Alloy 242-CD vs Alloy 242-SA
Nickel Alloy · Alloy 242 temper comparison
Alloy 242-CD and Alloy 242-SA are two conditions of the same nickel alloy grade, Alloy 242: CD (cold drawn) versus SA (solution annealed). The chemistry is identical, so every difference below comes from the condition. Alloy 242-CD is the stronger of the two: yield strength 750 MPa (109 ksi) against 375 MPa (54.4 ksi) for Alloy 242-SA, about 100% more; tensile strength follows at 1,000 MPa (145 ksi) vs 805 MPa (117 ksi). In exchange, Alloy 242-SA is the more ductile: elongation 48% versus 22% for Alloy 242-CD, and Alloy 242-CD is harder (286 HB vs 215 HB). Alloy 242-SA runs hotter in service (815°C vs 540°C continuous). On the shop floor, Alloy 242-SA welds better (good vs fair).

Alloy 242-SAChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Alloy 242-CD vs Alloy 242-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.
