Nickel Alloy M30C-AW vs M30C-F

Nickel Alloy · M30C temper comparison

M30C-AW and M30C-F are two conditions of the same nickel alloy grade, M30C: AW (as-welded deposit) versus F (as fabricated). The chemistry is identical, so every difference below comes from the condition. M30C-F is the stronger of the two: tensile strength 500 MPa (72.5 ksi) against 470 MPa (68.2 ksi) for M30C-AW, about 6% more. M30C-F is the more ductile: elongation 30% versus 22% for M30C-AW, and M30C-AW is harder (150 HB vs 140 HB).

M30C-FChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

M30C-AW vs M30C-F — frequently asked

Is M30C-F stronger than M30C-AW?

Yes. M30C-F has a typical tensile strength of 500 MPa (72.5 ksi) against 470 MPa (68.2 ksi) for M30C-AW — about 6% more.

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

F is the default M30C 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.

Which welds better, M30C-AW or M30C-F?

M30C-F. Its weldability rates good (68/100) against good (62/100) for M30C-AW.
