Titanium Grade 13 Annealed vs Grade 13-AW

Titanium · Grade 13 temper comparison

Grade 13 Annealed and Grade 13-AW are two conditions of the same titanium grade, Grade 13: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 240 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-welded deposit). Grade 13 Annealed is the more ductile: elongation 28% versus 18% for Grade 13-AW, and Grade 13-AW is harder (150 HB vs 130 HB).

Which condition does FabDigit quote by default, Annealed or AW?

Annealed is the default Grade 13 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 13 Annealed over Grade 13-AW?

Pick Grade 13 Annealed when the part is bent, formed or impact-loaded.
