powdercoating

hi there,
ive noticed a few folks have had their bikes powder coated, and i want to do the same to an old raleigh lugged steel frame i have but i was talking to the powder coater and he said the curing process on powder coat is 375 - 400 degrees for 20 minures. my question is...will this weaken the braze and weaken the steel in general?
id love to hear some opinions on this thanks!!!

No worry. The critical temp for steel is over 1000 degrees F.

im not really worried about the steel...im worried about the brazing metal ...its melting temp is less than the steel right? but still i dont think 375-400 would be too much....but not sure

we do powder coating at my shop and we frequently do lugged frames with no problem. the melting temperature for brass or even silver is higher than 400 degrees.

400 was probably picked because it is low end of significant effect on heat treatable steel. If you tig welded a frame, it might help relieve a little hardness, if it had any discernable effect at all.
