Steel Billets for Sugar Mill Shafts and Rollers
Sugar mills run heavy shafts and rollers under load through the crushing season. Billets and blooms are forged into shafts, pins and gear blanks for mill drives.
Typical components
- Roller shafts
- Gear shafts
- Pinions
- Couplings and bushings
Recommended steel grades
SAE 1045 / C45
A common medium carbon steel with good strength and machinability. Often used in the normalised or quenched and tempered condition.
EN8
General-purpose medium carbon steel with a good balance of strength and machinability. It responds to quenching and tempering in small and medium sections.
EN19
A widely used chrome-moly steel with good hardenability, toughness and fatigue strength in the quenched and tempered condition.
EN24
A high strength, deep hardening steel with very good toughness, used where heavy sections must harden right through.
SAE 4140
The American-designation counterpart of EN19 and 42CrMo4. Strong, tough and easy to heat treat.
Choosing the billet
Shaft makers should send finished diameters and lengths so a suitable bloom can be recommended.
Check the billet size chart for sections and weight per metre, and use the weight calculator for any length.
