Maximum possible DR...
Generally speaking, the limits of physical strength of materials are bounded by the interaction strength of electron bonds. Of course 'strength' is complicated, there's penetration resistance, melting/vaporization point, hardness and toughness which are different things, tensile, shear, and compression, etc.
But broadly speaking, about what would be the scientifically reasonable maximum theoretically possible DR material, in terms of conventional matter, say in the former of a uniform layer of the stuff an inch thick, or 2.54 centimeters if you prefer.

Though I suppose that would be more like HP, or at best ablative DR, since it isn't going to redistribute forces over its entire volume. It'd also be directional, for a 3D network I suppose it's about 70% of that. Stressing "reasonable" bit more than the "theoretical" one getting a non-ablative DR above 1000 or so is starting to look a little doubtful to me, but higher values might be reasonable enough approximations in some cases - sure the actual surface might start to show inch deep pits from multi-thousand hit point attacks, but if it's a thick enough plate on a huge object, those might pass off as "negligible scratches".

I assume you're using the DR 70 number. That's based on RHA, which is not a "moderately strong steel." So that theoretical super material is going to have about 150 times the tensile strength, for DR 10500 (860 if it should scale with square root). On the other hand, tensile strength is probably only one factor in a very complex equation.

Re: Maximum possible DR...
I'm kind of curious what non-conventional matter (like degenerate matter aka "neutronium") looks like in GURPS terms, but in normal terms it's not really relevant per inch, because you have to have an entire stellar mass worth of the stuff to have it at all.
Where it gets used in science fiction as super-high-tech hull material, it's firmly TL 12^ and held together with handwavium and force fields, so it's not the same sort of beast as the center of "a neutron star" or "a white dwarf" and has whatever stats have big enough numbers to be impressive. It does still tickle at the mind though.

It's way, way too late to reconcile those.
