Titanium ERTi-23-ANN vs ERTi-23-AW

Titanium · ERTi-23 temper comparison

ERTi-23-ANN and ERTi-23-AW are two conditions of the same titanium grade, ERTi-23: ANN (annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 830 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). ERTi-23-ANN is the more ductile: elongation 15% versus 12% for ERTi-23-AW, and ERTi-23-AW is harder (34 HRC vs 32 HRC).

ERTi-23-ANN vs ERTi-23-AW — frequently asked

What is the difference between ERTi-23-ANN and ERTi-23-AW?

ERTi-23-ANN and ERTi-23-AW are two conditions of the same titanium grade, ERTi-23: ANN (annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 830 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).

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

AW is the default ERTi-23 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 ERTi-23-ANN over ERTi-23-AW?

Pick ERTi-23-ANN when the part is bent, formed or impact-loaded.
