Refractory Metal 50Cr-50Ni-Cb-AC vs 50Cr-50Ni-Cb-AW

Refractory Metal · 50Cr-50Ni-Cb temper comparison

50Cr-50Ni-Cb-AC and 50Cr-50Ni-Cb-AW are two conditions of the same refractory metal grade, 50Cr-50Ni-Cb: AC (spheroidize annealed) versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. 50Cr-50Ni-Cb-AC is the stronger of the two: tensile strength 590 MPa (85.6 ksi) against 560 MPa (81.2 ksi) for 50Cr-50Ni-Cb-AW, about 5% more. 50Cr-50Ni-Cb-AC is the more ductile: elongation 8% versus 5% for 50Cr-50Ni-Cb-AW, and 50Cr-50Ni-Cb-AW is harder (19 HRC vs 16 HRC).

50Cr-50Ni-Cb-AC vs 50Cr-50Ni-Cb-AW — frequently asked

Is 50Cr-50Ni-Cb-AC stronger than 50Cr-50Ni-Cb-AW?

Yes. 50Cr-50Ni-Cb-AC has a typical tensile strength of 590 MPa (85.6 ksi) against 560 MPa (81.2 ksi) for 50Cr-50Ni-Cb-AW — about 5% more.

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

AC is the default 50Cr-50Ni-Cb 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, 50Cr-50Ni-Cb-AC or 50Cr-50Ni-Cb-AW?

50Cr-50Ni-Cb-AC. Its weldability rates poor (25/100) against poor (20/100) for 50Cr-50Ni-Cb-AW.
