Nickel Alloy Alloy 242 Aged vs Alloy 242-CD

Nickel Alloy · Alloy 242 temper comparison

Alloy 242 Aged and Alloy 242-CD are two conditions of the same nickel alloy grade, Alloy 242: Aged (SA + Aged) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. Alloy 242 Aged is the stronger of the two: yield strength 850 MPa (123 ksi) against 750 MPa (109 ksi) for Alloy 242-CD, about 13% more; tensile strength follows at 1,210 MPa (175 ksi) vs 1,000 MPa (145 ksi). Alloy 242-CD is harder — 286 HB against 215 HB for Alloy 242 Aged — which matters for wear surfaces and threads. Alloy 242 Aged runs hotter in service (815°C vs 540°C continuous). On the shop floor, Alloy 242-CD welds better (45 vs 35 out of 100).
