SS316 Clad Vessel vs SS316 Solid

SS316 Clad Vessel vs SS316 Solid

Hi everyone,

Is it true that for SS316 cladded vessel, it could withstand higher/ more severe conditions (chloride, temp, etc) than solid SS316L vessel?
SCC generally requires tensile stress, appropriate corrosive species and material susceptible to SCC (this case austenitic). DOes cladding removed the tensile stress and always in compression mode hence the chance of SCC is low to none?

Thanks a lot.

RE: SS316 Clad Vessel vs SS316 Solid

No, but in some cases it can help.
Still plenty of opportunity for localized tensile stress.
What temp?
Temp cycling?

RE: SS316 Clad Vessel vs SS316 Solid

If SCC does occur in the cladding, it will not lead to rapid failure of the vessel. Clad vs solid is chosen for this reason or for economic reasons. Remember that the stainless steel cladding can be roll clad, explosion clad, of weld overlayed.

RE: SS316 Clad Vessel vs SS316 Solid

Tensile stresses sufficient to qualify for chloride SCC are a given, especially in a vessel. When doing failure investigations involving SCC I usually don't need to look very far to find potential sources of tensile stress, either residual or applied.

Differential thermal expansion between the stainless clad and the steel substrate causes significant interface shear stress all by itself.

I agree with ironic metallurgist.
