    Well the client asked for the exact material if possible so thats what we're trying for. I mean its held up for 15 yrs., why go and change it now. But I think your right on track with the refractaloy. I had forgot we use to drill out the studs on turbine decks and the material of the studs then...

    If not for the cobalt I would identify it as a incoloy 925 as SMF1964 said or incoloy 825. Also some of the inconel alloys come very close, but lack the iron. But as this project is getting close to start we are leaning towards the waspaloy, the only problem with the waspaloy is the lack of...

    If you are referring to incoloy 925, the cobalt content rules the incoloy out. Incoloy was my first guess also until the I saw the cobalt at 12.7%.

    Yes I agree that some of the numbers don't seem right, however, this stud has been in operation for some 10 - 15 years. Now I'm not sure if that many years of operation at that temp. could change the chemistry or the harness. Yall would know better than me. But if we knew when, who, and where...

    It is a steam turbine but I don't know the operating temperature. But I would assume 1,000°F to 1,200°F.

    One more thing, when the testing laboratory ran the spectroscopy, their database came back with a "close" match of waspaloy. Now the chemistry on waspaloy looks very close to this except the iron. Waspaloy has 2% max iron and as you can see my unknown has 19.3. Again any help is appreciated.

    We obtained the chemistry by performing a spark emission spectroscopy on the stud. Also a hardness survey was done and came out a 31 HRC. The stud was removed onsite and sent in by the customer. They need 100 manufactured but don't have any material specs on the stud.

    The chemistry is as follows: Carbon 0.05 Sulfur 0.004 Silicon 0.08 Manganese 0.10 Iron 19.3 Chromium 21.5 Molybdenum 2.79 Copper 0.01 Aluminum 0.25 Titanium 3.53 Cobalt 12.7 Nickel Matrix The chemistry is of a 1.5" stud from a large...
