Nickel Alloy CZ-100-F vs CZ-100-SR

Nickel Alloy · CZ-100 temper comparison

CZ-100-F and CZ-100-SR are two conditions of the same nickel alloy grade, CZ-100: F (as fabricated) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. CZ-100-F is the stronger of the two: yield strength 160 MPa (23.2 ksi) against 150 MPa (21.8 ksi) for CZ-100-SR, about 7% more. In exchange, CZ-100-SR is the more ductile: elongation 28% versus 25% for CZ-100-F, and CZ-100-F is harder (62 HRB vs 58 HRB).

CZ-100-FChoose it when strength drives the design.

CZ-100-SRChoose it when the part is bent, formed or impact-loaded.

CZ-100-F vs CZ-100-SR — frequently asked

Is CZ-100-F stronger than CZ-100-SR?

Yes. CZ-100-F has a typical yield strength of 160 MPa (23.2 ksi) against 150 MPa (21.8 ksi) for CZ-100-SR — about 7% more. Tensile strength is 380 MPa (55.1 ksi) vs 370 MPa (53.7 ksi).

Which condition does FabDigit quote by default, F or SR?

F is the default CZ-100 condition in the FabDigit quote flow. 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 CZ-100-F over CZ-100-SR?

Pick CZ-100-F when strength drives the design. Pick CZ-100-SR when the part is bent, formed or impact-loaded.
