In terms of materials wouldn't it be better to assume that the technology to make something like this is way beyond what we have today, so it's best to create estimates using the strongest materials we currently know of, rather than can easily manufacture? (I am not a physicist, just think that any mention of steel in construction of a titan seems at odds).
So we'd see the use of carbon nanotubes or even boron nanotubes wouldn't we? How would that change the weight and feasibility of such a structure?

Of course, as Peregrine says, you don't really have enough information to be able to do that either, in any meaningful way. 
That's a good point and sorry for not clarifying that's along the lines of what I meant - when people talk about the square-cube law, they use the properties of steel, rather than something cutting edge. It'd just be interesting to see how much more feasible it would be using the most advanced materials we have today, as opposed to most of the debate ranging from "steel can only cope with x" and then "yeah but it's made out of adamantium and plasteel."
As you said, it's not really possible, but mentioning steel anywhere within this context seems erroneous at best.

Burj Khalifa. 800m high. Built out of commonly available material's. Nothing wrong with steel 
I see your point  wouldn't a walking, firing Titan have to be endure a lot more and different stresses on its hull? Even just the shock of a step would require extremely strong materials.

First of all: since when is an imperetor class titan only 50m tall!? They're always made to look so much bigger...
40K lore being the prolonged thing it is, no piece of literature in it has clearly stated the height of any Titan outside of the ones that are actually models; we've had this problem with Warlords up till recently - some artwork and games like Space Marine depicted them as being 2 or 300 metres tall, while other art has said they are much smaller than that.
I guess I'll repeat what everyone else has said - these things are made of materials that don't exist on Earth and probably don't exist in the galaxy either; we can't really work out their weight unless GW wrote something clearly stating their weight.
I wouldn't hold your breath on that.
Still, I like your idea of finding this out, so if you really wanted to estimate this, perhaps class Plasteel as having a similar weight to steel per KG/Pound and Ceramite being similar to a ceramic plating material per KG/Pound.
I don't reckon you'll be able to do anything but wildly guess this one, but you seem pretty determined and I wouldn't want to stamp out your figurative campfire
Hope this helped in some way.
G.A
the problem with your assumption is Plasteel is useally presented across sci-fi as being a super material that is "light as plastic, tough as steel" so I think we'd be better off assuming plasteel was lighter then steel
Don't carbon nanotubes already outperform plasteel?

It might do, but that's what shock absorbers are for. Also steel is extremely strong already which is why we build really big things out of it.
Automatically Appended Next Post:
Also some plastics are already tougher than steel, just not necessarily as strong. Also also carbon nanotubes are all very well but they're a bugger to make into antrying larger than a nanotubes. Resins tend to go squishy in any conditions warmer than a hot day (/artistic licence)
I know the yields of carbon nanotubes are non-existent at the moment but there wouldn't be musings to use it as the building blocks of a space elevator if it wasn't feasible to eventually make large quantities of the stuff. Just saying that steel and plastic are good and all but they're not cutting edge.
