Requirements for stress relief of Hastalloy piping

[ledon]

I was wondering if there are any stress relief or other heat treat requirements for hastalloy piping after welding. This is a new material for me. The piping is for chemical service essentially non-corrosive at moderate temperatures.

No, this material can be left in the as-welded condition.

And as you look for info, you be more specific : Hastalloy...B , C ,C4 , C276 ( B in particular is rather different from the others).

Sorry. To be more specific Hastalloy c276. Thanks for the insight.
