Steel discs

I'm looking for some steel discs to buy,

They are weights for a project I hope to start.
Ideal size 120mm diameter 10mm thick.
the size can be 50% in either direction as I can make the thing to fit the discs.
Ideally about 10 off or more, material steel.

They can have a lead in on them, and don't have to have a pilot bore, tolerance is not an issue as I can adjust the weight.

I am ideally looking for scrap, where a process has plasma cut some holes in a plate for something and the discs are scrap.

Thanks for your help

maybe on the pricey side http://www.ebay.co.uk/itm/10mm-Mild-...item4ab8d1cd72

6" and 6mm thick weighs about the same as 10mm thick and 120mm diameter. Lots cheaper.
