Stess Relieving

[creynolds]

I'm trying to find out what temperature I should use to stress relieve 1"x3/4" 1020 DOM that has been tig welded using er70s-2. I have a call in to my local Prax-air, however they are sometimes slow to respond. Does anyone know of a website that contains information like this on different grades of steel?

Thanks,
Cord

why do you need it stress relieved?
i do tons of rollers every week and very rarely do we stress relieve anything...

but in the real world..this is tubing i suppose..
to do it correctly you need to turn the scale off the o.d. FIRST..
then it needs to go in a oven to bake for awhile around 600 degrees
and let cool in the oven after its shut off overnite...
i could be wrong about the temp but thats the procedure...

The fabrication is being done on a 67 cadillac so I thought it might be a good idea to stress relieve the welds on the cross members/frame etc. The plan was to purchase some temperature sticks from the local welding supply and stress relieve with O/A and temp stick. Is this not a sufficient method? Or maybe not even worth doing.
