Could Deadlight wrecks supply low-background steel?

Could the steel from the scuttled U-boats be salvaged as pre-atomic or low-background steel?

Technically it could be useful, but salvage would require agreement from Britain, the United States, and Russia as the successor to the Soviet claim.

Pre-atomic steel had attracted proposals to recover material from the wrecks. The obstacle described here is the need for British, American and Russian approval. Potential financial benefits would not guarantee agreement between the governments. The suggestion that one government might refuse because another had agreed is a speculative comment on their relations.
