SA 302 grade C drum manufacturing
SA 302 grade C drum manufacturing
(OP)
Hi,
I'm looking for anyone familiar with using SA 302C plate material for drums or pressure vessels. Are their any procedure recommendations for rolling or forming this material for drum shells and heads? I realize code requires this material to be PWHT when welded, but I am more interested in heat treatments used before, during and after rolling and forming of the plate. Is it common to apply heat, re-normalize, or anything of the sort?
Any help would be appreciated.

Caution: Manganese- Nickel- Molybdenum alloys have higher hardenability than Carbon-Molybdenum alloys and greater preheating will be required, especially for thick items to eliminate cold cracking. Also these alloys have a much greater potential for temper embrittlement at high operating temperatures than C-Mo alloy steels.
They can be manufactured to provide high toughness at temperatures below -50F in heavy wall thickness.
