Letter 11016

Does a S-N curve for PtRh20 or PtRh10 exist for elevated temperatures???  

Where can I find an S-N fatigue curve for PtRh20 alloy material? I need the curve in order to determine the number of fatigue life cycles of a PtRh20 manufactured stirrer in liquid glass. It would be great to have this S-N curve at room temperature, but it would even be greater to receive one for elevated temperatures (f.e. 1000 or 1100 degrees).

Thanks in Advance,
