Titanium C-1-F vs C-1-HIP

Titanium · C-1 temper comparison

C-1-F and C-1-HIP are two conditions of the same titanium grade, C-1: F (as fabricated) versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. Both yield at about 210 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as fabricated versus hot isostatic pressed). C-1-HIP is the more ductile: elongation 25% versus 20% for C-1-F.

C-1-HIPChoose it when the part is bent, formed or impact-loaded.

C-1-F vs C-1-HIP — frequently asked

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

C-1-F and C-1-HIP are two conditions of the same titanium grade, C-1: F (as fabricated) versus HIP (hot isostatic pressed). The chemistry is identical, so every difference below comes from the condition. Both yield at about 210 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as fabricated versus hot isostatic pressed).

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

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-F over C-1-HIP?

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