Titanium Grade C-2-F vs Grade C-2-SR

Titanium · Grade C-2 temper comparison

Grade C-2-F and Grade C-2-SR are two conditions of the same titanium grade, Grade C-2: F (as fabricated) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. Grade C-2-F is the stronger of the two: yield strength 385 MPa (55.8 ksi) against 365 MPa (52.9 ksi) for Grade C-2-SR, about 5% more. In exchange, Grade C-2-SR is the more ductile: elongation 18% versus 16% for Grade C-2-F.

Grade C-2-FChoose it when strength drives the design.

Grade C-2-SRChoose it when the part is bent, formed or impact-loaded.

Grade C-2-F vs Grade C-2-SR — frequently asked

Is Grade C-2-F stronger than Grade C-2-SR?

Yes. Grade C-2-F has a typical yield strength of 385 MPa (55.8 ksi) against 365 MPa (52.9 ksi) for Grade C-2-SR — about 5% more. Tensile strength is 480 MPa (69.6 ksi) vs 465 MPa (67.4 ksi).

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

F is the default Grade C-2 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 Grade C-2-F over Grade C-2-SR?

Pick Grade C-2-F when strength drives the design. Pick Grade C-2-SR when the part is bent, formed or impact-loaded.
