Titanium C-1-ANN vs C-1-F

Titanium · C-1 temper comparison

C-1-ANN and C-1-F are two conditions of the same titanium grade, C-1: ANN (annealed) versus F (as fabricated). The chemistry is identical, so every difference below comes from the condition. Both yield at about 200 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (annealed versus as fabricated). C-1-ANN is the more ductile: elongation 24% versus 20% for C-1-F, and C-1-F is harder (130 HV vs 122 HV).

C-1-ANN vs C-1-F — frequently asked

What is the difference between C-1-ANN and C-1-F?

C-1-ANN and C-1-F are two conditions of the same titanium grade, C-1: ANN (annealed) versus F (as fabricated). The chemistry is identical, so every difference below comes from the condition. Both yield at about 200 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (annealed versus as fabricated).

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

F is the default C-1 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 C-1-ANN over C-1-F?

Pick C-1-ANN when the part is bent, formed or impact-loaded.
