What temperature would a 4130N tube frame be stress relieved at? Is there a critical temperature to stay away from as to not change properties? This will be done in an oven.

RE: 4130 Stess relief
Some codes however, such as NACE MR 01 75 specify minimum temperatures for stress relieving and then life can get complicated - so check that no specific codes apply to your weldment.
