Titanium ERTi-11-AW vs ERTi-11 PWHT

Titanium · ERTi-11 temper comparison

ERTi-11-AW and ERTi-11 PWHT are two conditions of the same titanium grade, ERTi-11: AW (as-welded deposit) versus PWHT (post-weld heat treated). 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 (as-welded deposit versus post-weld heat treated). ERTi-11 PWHT is the more ductile: elongation 32% versus 28% for ERTi-11-AW, and ERTi-11-AW is harder (125 HB vs 118 HB).

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

AW is the default ERTi-11 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-11-AW over ERTi-11 PWHT?

Pick ERTi-11 PWHT when the part is bent, formed or impact-loaded.
