Lukens' clad steel is a composite plate developed to provide at a lower cost the benefits of expensive materials. It consists of two metals which have been mill rolled under heat and pressure until they are integrally bonded over their entire interface. Recently, this technology has been extended to include INCONEL alloy 625 in the family of nickel base alloys clad to steel. Bend, tensile, and shear tests taken from plates with INCONEL alloy 625 as the cladding conform to ASTM A265-81, the standard specification for nickel and nickel base alloy clad steel plate. In addition, weld tests conducted in the laboratory have shown that shielded metal are welds provide good structural integrity.

Test panels from INCONEL 625 clad plate were successfully installed in two wet flue gas scrubber systems. In one system INCONEL 625 clad plate was located in the roof section of the absorber just ahead of the outlet ducting. The test plates, including weld seams, showed no signs to corrosion after six months of exposure. In the other scrubber test plates located in the outlet duct of an I.D. fan house, in the stack lining, and in the absorber quench area were unattacked after nine months.
