RE: Normalizing of dish ends
one place I know about is UCS-75 (or maybe UCS-57). There you have a formula to calculate the extent of coldwork when forming the head. It has a limit above which you are required to normalize the head(or even the shell if the limits apply)
hope it helps
RE: Normalizing of dish ends
If you are normalising the heads after cold forming, mechanical test has to be carried out after normalising. This mechanical test can be avoided if the original material is in the normalised condition
