Nickel Alloy N07773-CD vs N07773-STA

Nickel Alloy · N07773 temper comparison

N07773-CD and N07773-STA are two conditions of the same nickel alloy grade, N07773: CD (cold drawn) versus STA (solution treated and aged). The chemistry is identical, so every difference below comes from the condition. N07773-CD is the stronger of the two: yield strength 1,100 MPa (160 ksi) against 1,030 MPa (149 ksi) for N07773-STA, about 7% more. In exchange, N07773-STA is the more ductile: elongation 16% versus 12% for N07773-CD, and N07773-CD is harder (375 HB vs 350 HB).
