Nickel Alloy Nimonic 86-CD vs Nimonic 86-SA

Nickel Alloy · Nimonic 86 temper comparison

Nimonic 86-CD and Nimonic 86-SA are two conditions of the same nickel alloy grade, Nimonic 86: CD (cold drawn) versus SA (solution Annealed). The chemistry is identical, so every difference below comes from the condition. Nimonic 86-CD is the stronger of the two: yield strength 700 MPa (102 ksi) against 380 MPa (55.1 ksi) for Nimonic 86-SA, about 84% more; tensile strength follows at 950 MPa (138 ksi) vs 800 MPa (116 ksi). In exchange, Nimonic 86-SA is the more ductile: elongation 48% versus 25% for Nimonic 86-CD, and Nimonic 86-CD is harder (260 HB vs 195 HB). Nimonic 86-SA runs hotter in service (1,100°C vs 600°C continuous). On the shop floor, Nimonic 86-SA welds better (very good vs good).
