Nickel Alloy N06255-CD vs N06255 CD+SR

Nickel Alloy · N06255 temper comparison

N06255-CD and N06255 CD+SR are two conditions of the same nickel alloy grade, N06255: CD (cold drawn) versus CD+SR (cold worked and stress relieved). The chemistry is identical, so every difference below comes from the condition. N06255-CD is the stronger of the two: yield strength 700 MPa (102 ksi) against 640 MPa (92.8 ksi) for N06255 CD+SR, about 9% more; tensile strength follows at 950 MPa (138 ksi) vs 900 MPa (131 ksi). In exchange, N06255 CD+SR is the more ductile: elongation 28% versus 25% for N06255-CD, and N06255 CD+SR is harder (101 HRB vs 89 HRB).

N06255-CDChoose it when strength drives the design.

N06255 CD+SRChoose it when the part is bent, formed or impact-loaded.

N06255-CD vs N06255 CD+SR — frequently asked

Is N06255-CD stronger than N06255 CD+SR?

Yes. N06255-CD has a typical yield strength of 700 MPa (102 ksi) against 640 MPa (92.8 ksi) for N06255 CD+SR — about 9% more. Tensile strength is 950 MPa (138 ksi) vs 900 MPa (131 ksi).

Which condition does FabDigit quote by default, CD or CD+SR?

SA is the default N06255 condition in the FabDigit quote flow (neither CD nor CD+SR). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

When should I choose N06255-CD over N06255 CD+SR?

Pick N06255-CD when strength drives the design. Pick N06255 CD+SR when the part is bent, formed or impact-loaded.
