200 mm Round Steel Billets: supply
We make 200 mm diameter steel billets in all grades of carbon, alloy and stainless steel, supplied as cast.
As a 200 mm diameter billet supplier we cut to length or supply up to 12 metres. These are round as cast steel billets, so surface finish and any grinding are agreed at order.
Choose round when the forging or ring starts round, so the reduction is even around the section.
Typical forged and rolled parts
- Ring rolling blanks
- Gear blanks and discs
- Round shafts and hubs
- Bearing race rings (bearing grades)
