[PSUBS-MAILIST] Cold verses Hot rolled Tee rings ?

[hank pronk via Personal_Submersibles]

 Ian,Why T rings, it might be cheaper and for sure super accurate to cut rings from plate.  You can have rings cut in halves or thirds to save material.  Gamma has solid rings internal instead of T bars.  Just an option.Hank

 Ian,
      What I did was to order vertical and horizontal rings and weld them.

Hi sub folks,

for my K250 (VAST MKIII type) resto-mod I'm planning on adding external re-enforcing rings.

I recently got a quote for some hot rolled T rings (1-1/2 x 1-1/2 x 1/4 OD 39" out-of-round tolerance %1) for ~$800 + shipping.  Since it was the only place that replied to my quote request, I'm thinking of going with them.

I know cold rolled is dimensionally more accurate, but is going with hot rolled going to cause me issues?

Thanks,
  Ian.
