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

[irox via Personal_Submersibles]

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.
