We have cast a Austenitic Stainless Steel, but a few litle hot tearaing remains.
If we try to open the crack we can show a propagation of this crack. The parts seems have a higer internal stress. This can provide from a higher level of internal stress.
1- Can i use a stress relief heat treatment to reduce this internal stress like after welding ? but i have not welded or repaired this partr yet !
2- What about the stress relief heat treatment of Austenitic Stainless Steel? what is the best temperature ?
