Cold Rolling SA387 Gr.91 Plate
Cold Rolling SA387 Gr.91 Plate
(OP)
Hi,
Does anyone know of any precautions needed for cold rolling Grade 91 Chromoly plate.
The plate will be 3/8" thick and rolled to form a cone with a small diameter of approx. 10" and approx. 20 inches long.
I will PWHT the long seam as normal.
Please note, this cone will not be part of the pressure bearing wall.
Thanks

As always, you reply with great sense.
I have just read ASME Sec. 1, PG-20. I am going to study this a bit more and will make my decision based on this.
Thanks Again.

If you're going to make a bunch of these, several grinding companies have hand-operated edge bevelers that will save a lot of time over hand-grinding.
