I'm an old fart.
They started putting disks on production bikes about 1968-69.
There was a lot of experimenting with different compounds by the bike manufacturers. Some used cast iron and some used steel and some had problems at first with things like shattering disks and warping etc.
I think it was Greg Hansford that had a disk explode coming down Conrod Straight the first year they tried them at Bathurst. I've got no idea what sort of material it was.
I have just researched this . It appears that they use a "high carbon content 400 series (martensitic) stainless steel" or "420 stainless".
