The crack still appearance after certain period of operation in the event repair on the weld joint area has been performed few times. The exhaust material is SS 316L.
It's suspected by high exhaust temperature operating (500 deg. C) that caused thermal stress on welding joint area.
Thanks to somebody that can assist by detailing information on vendor website, email address and contact person.
