Hi mr. Jignesh
I have come across some failure cases of austenitic stainless steel dished ends due to high hardness.
Now the issue is there are some ASS equipment intended to use in h2s service in a petrochemical plant. Few equipment delivered and hardness check on production dished ends revealed > 300BHN. Is it advisable to  do stress relieving of the delivered equipment at site at 400ºC for one hour.
