Ken, I will have to withdraw my comment about the chrome surfacing.

Since the idea was to apply the steel cladding to a aluminum sheet and then
furnace braze

the part to an end housing nitriding might be too hot a process for the

binding material used in the AL braze process. (Gas Nitride is usually done
at about

900°F) The fact is that the aluminum will nitride as well which might

make it brittle.

Just a comment while on this subject.
We made several sets of lightweight titanium wristpins for testing
on endurance type V-8 racing engines.
They were gas ion nitrided, and run with no problems for many
races. Upon disassembly, no apparent problems, and were
re-used again. At this point, not sure if the cost of fabrication
is justified, however.
