There is no datasheet, there is a piece of pipe we did PMI, replica, and hardness, and found it Incoloy alloy 825,no wi need to know Specified Minimum Yield Strength and relevant ASTM standrad.
tnx
You need to find out what specification it was manufactured to. Other wise the only option is to use the lowest of the allowed strength for any tubular product form.
If this a Code application? If so then you have a lot of work to do.
