Don't worry, RAN, back in my days of erector engineer, I've done that plenty of times and no plant busted because of that.
A word of warning, though !
You can do that on austenitic stainless steels (and 304L is one of them) and in ferritic stainless steels, because they don't change their metallurgical structure no matter the temperature changes.
You can also do that on low carbon steels because the carbon content isn't high enough to change the metallurgical structure significantly.
BUT, you can not do that on martensitic stainless steels (AISI Tp 410 is one) nor on chrome - moly low alloy steels because they'll develop a high hardness, which is harmful to the material.
