George,
 The bond created by the cladding process is as
good as it gets. There still is differential expansion to
be concerned with. When you have a bond on the
molecular level you need to study which portion of
the assembly has the highest mechanical stiffness.
The plate brazed to the end or intermediate housing
should be more flexible than the housing itself. Ironically
this would dictate a THINNER steel plate which
is what we want anyway!
Bill Jepson

Don't forget the steel runs hotter than the aluminum so there is some
compensation there.
