PRESSURE VESSEL WITH AISI 4140 SHELL
PRESSURE VESSEL WITH AISI 4140 SHELL
(OP)
Is there anything in Sect.VIII or Sect.IX that permits welding of a shell material with .42% carbon content to a one piece head/journal of SA36? I need a welded connection so I can't use a bolt on journal. SA649 cannot be used as the final hardness requirement will be less than that specfied.

Section IX does not provide guidance on maximum carbon content limitations of base materials. It provides a listing of ASME B&PV code acceptable materials and their classification (P-number) related to weldability.
