Debasis SS 410 cladding (explosion bonding) can create problems if cladded plates are not normalized and stress relieved (as far as i know) If it is martensitic SS 410 then problems can be more. Welding procedure at site will also have to be done carefully. If this is not done properly you will get cracks easily which will penetrate to the parent backing C.S material.
