WW1 German shipwreck steel has been salvaged and used for shielding of
nuclear sensors, since it wasn't contaminated with fallout or
nuke-produced carbon-14 like modern steel.
The difference is that these ships were scuttled in Scapa Flow and are
not war graves. Scapa Flow has a max depth of 200 ft or so making
conventional salvage relatively easy moreover the Admiralty wanted most
of the wrecks lifted to make it usable as a base.
More reprehensible has the stripping of HMS Prince of Wales, Repulse and
her escorts which are war graves. It is a fine line though. The Tirpitz
was salvaged by the Norwegians after the war but the wreck was an
environmental catastrophe and the Norwegians recovered what bodies they
could find for burial.
