SAW flux recommendations for Stainless Steel

[JoAH]

While we weld stainless steel with some regularity, the need for SAW is infrequent. We will be making both circumferential and longitudinal seams in some 4ft. diameter drums, 5/8 in. thick, 304L. (non-corrosive, not wetted) The existing SAW WPS flux is no longer available. I am looking for some USER recommendations as to what brand & type flux has provided the best results.

I am certain you will need to requalify, since SS fluxes come with varying amounts of chromium addition, and this is a variable in ASME IX. For sure you will want to runs some trials to optimize the new parameters.
ESAB, Oerlikon, and Thyssen have excellent products. Contact
