Nickel Alloy ERNiCrFe-11-AW vs ERNiCrFe-11 PWHT

Nickel Alloy · ERNiCrFe-11 temper comparison

ERNiCrFe-11-AW and ERNiCrFe-11 PWHT are two conditions of the same nickel alloy grade, ERNiCrFe-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 420 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). ERNiCrFe-11-AW is the more ductile: elongation 40% versus 35% for ERNiCrFe-11 PWHT, and ERNiCrFe-11 PWHT is harder (16 HRC vs 14 HRC).

ERNiCrFe-11-AW vs ERNiCrFe-11 PWHT — frequently asked

What is the difference between ERNiCrFe-11-AW and ERNiCrFe-11 PWHT?

ERNiCrFe-11-AW and ERNiCrFe-11 PWHT are two conditions of the same nickel alloy grade, ERNiCrFe-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 420 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).

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

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

Pick ERNiCrFe-11-AW when the part is bent, formed or impact-loaded.
