Sourcing Bright Flat Steel Bar

Hi,



I have a small project underway to fit a new QCTP to my lathe, where I need some 120 x 15mm (approx) flat bar about 300mm length, all I have managed to obtain in Melbourne is flat black hot rolled steel with that hard crust on it, I have milled that off but the finish is not great.



Does anyone know where in Melbourne to get small lengths of bright in those approximate dimensions



Thanks..



Eric
