Does UCL apply to cladding on tubesheet?

[HungM]

Hi,

I have a question about the scope of ASME UCL. For a stainless steel STHE made with SA-240 304L on both sides, using an SA-965 F304L tubesheet with a corrosion-resistant cladding, and no welding to the cladding. Would this STHE fall under the scope of UCL rules?

Please share your insights

What corrosion resistant cladding material are you planning? Your base material SA-965 F304L itself is corrosion resistant.
