If China is successful in shutting down UK's last blast furnace, the AUKUS subs are...well...sunk. We can't ship Oz steel to the US (tariffs) and we can't afford to buy theirs.
It’s not British steel in the Dreadnaught and I presume the same will be true for SSN-A. Australia will build most of their own apart from the reactor module anyway.
