Nickel Alloy Alloy 120-CD vs Alloy 120 HR-ANN

Nickel Alloy · Alloy 120 temper comparison

Alloy 120-CD and Alloy 120 HR-ANN are two conditions of the same nickel alloy grade, Alloy 120: CD (cold drawn) versus HR-ANN (hot Rolled + Annealed). The chemistry is identical, so every difference below comes from the condition. Alloy 120-CD is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 310 MPa (45 ksi) for Alloy 120 HR-ANN, about 100% more; tensile strength follows at 900 MPa (131 ksi) vs 720 MPa (104 ksi). In exchange, Alloy 120 HR-ANN is the more ductile: elongation 47% versus 20% for Alloy 120-CD, and Alloy 120-CD is harder (250 HB vs 158 HB). Alloy 120 HR-ANN runs hotter in service (1,149°C vs 650°C continuous). On the shop floor, Alloy 120 HR-ANN welds better (very good vs good).
