[MW:7589] forming head

Hello All,
We are going to form a head for a presser vessel. Its diameter is about 3000mm.
And it is made of A516Grade70. Unfortunately, while forming we have cracks on
the material which cause rejection of the head.
How can we form a crack-free head? Do we have to do the forming in several
steps? Do we need heat treatment between forming steps?
Thank you,
Saied
