Large Diameter super-duplex heads.

Large Diameter super-duplex heads.

(OP)
I have a need for some large diameter super duplex head that will have to be manufactured in two (2)welded together prior to forming.  Our suppliers here can not get the plates to quenching fast enough after annealing so the welds will be crack sensitive.   Where do you guys buy these large diameter  120" to 156" i.d.  2:1 elliptical.

RE: Large Diameter super-duplex heads.

(OP)
none of these can do it

we have gone to anonius in the netherlands

and brighton with an alternate of AL6XN

RE: Large Diameter super-duplex heads.

Did you try Europe ( France, Italy, Spain, Belgium) for diameters to 4.2 m made of Uranus 52 N?
Also, a couple of major Indian suppliers could help you, same Uranus 52 N or even 2507.
Thickness to 5" in Spain.
Caution;- dished end forming of this material would invariably force you to compromise the theoretical shape, so be prepared.
Cheers,
