I have a requirement of vessel of SA 516 Gr 70+ ss304L CLADDING.
Vessel requires PWHT.
I am aware that to avoid sensitization, pwht cycle of ss cladded vessel is such that soaking temperature is reduced & soaking time is increased. (soaking temp 510 degree cel. Soaking time 10 hours/inch)
But now due to low carbon grade of SS i.e. ss304L, can I follow the soaking time & temp as UCS-56 cycle ?
i.e. I want to have pwht at 610 degree cel with time as per UCS-56.
