Hi Glen.

Not saying this is the only one you could use, but im using ER70S-6.  Trade 
name is Lincoln Supramig ultra.

Minimum tensile strength 70,000psi (the same as the "GR70" on your base 
material.
Low Hydrogen (mig is generally low hydrogen anyway)
Low silicon deposit on the completed bead
and according to the box, "provides better wet-in for applications subject 
to fatigue" (like a submarine under pressure cycling).

Sorry, i cant help with the South Africa subs though.

Regards
James
