stress releif of 356 Aluminum
(OP)
I'm hoping I can avoid a trip to the local university to check the ASTM materials book. Can anyone tell me the procedure for stress relieving 356-T6 (time and temp)? I'm having problems with a plate that doesn't want to stay flat when pulled out of the mill. I'm thinking it is has too much residual stress from the casting process. Would the part normally be laid flat in the oven?

"After the cryogenic process we do heat up the parts to 300 degrees F. to stabilize the material. Or parts are run through an artificial aging process after cryotreating. During the artificial aging process parts are heated up to 500 degrees F."
My question: Wouldn't heating it to 500 F decrease the strength significantly?
