1. A clad system comprising:
a. a first layer of niobium;
b. a second layer of stainless steel; and
c. a liner consisting of a single metal, wherein the first layer, the liner, and the second layer are cladded to one another, with the liner adjacent to and between the first layer and the second layer, to create the clad system, wherein the liner is configured to allow the clad system to be resistant to forming intermetallics between the first layer and the second layer, and wherein the single metal of the liner comprises an elevated melting temperature compared to the first and second layers, preventing the liner from substantially diffusing into the first layer or the second layer.
