I have stock of literally MILLION of steel balls.
These are industrial grade balls made to be used in ball bearings.
I have both Stainless steel balls and High carbon steel balls.
Some of my High carbon steel balls are made of 5160 spring steel and are awesome to be used to make ball bearing damascus knives.
The stainless steel balls are 304 stainless highly polished balls.
Again you can buy the balls on eBay http://stores.ebay.com.au/Gelandangan-BrickaBracks
Or if you want them in bulk (minimum of $1000 in total purchase price) please contact me directly.
