BUMAX 109 is the 10.9 equivelant grade, although you can get it exceeding this.
The properties seem to be a good match, with the added bonus of being better than A4 for corrosion resistance.

High Tensile Stainless Bolts
I just discovered these, not sure if anyone has come across them before.BUMAX, a type of stainless fastener that matches (and in some aspects exceeds) the strength of 10.9 grade bolts that we use for our suspension & other bits we don't want to move.
