Forming of large-diameter stainless steel heads
Thread Content
Dear all: There are two DN4200x22 duplex stainless steel end caps. Can these end caps be formed by cold stamping? Is it possible to carry out solution treatment after shaping?
It’s so large; it must have been spun. For stamping, molds are not necessarily required. If the wall thickness is not large, according to 150, as long as the deformation amount does not exceed the limit. 15% is not an easy target to achieve, with such a large diameter.

Housings of such large diameter are generally formed by spinning, and solution treatment should be carried out after formation.
The spin-forming machines currently available in the country are more than sufficient to meet the requirements for spin-forming; stamping is also an option, and specialized head manufacturers have the necessary equipment for pressing and shaping heads.
Spin forming is carried out, followed by heating to around 1200°C and holding at that temperature for 40 minutes; subsequent water cooling is used for solution treatment.
