Steel Billets for Fasteners and Bolts
High strength fasteners are upset and forged from billet stock. Chemistry and cleanliness control the heat-treated strength and the fatigue life of the bolt.
Typical components
- High tensile bolts
- Studs and threaded fasteners
- Anchor bolts
- Nuts and washers
Recommended steel grades
SAE 4140
The American-designation counterpart of EN19 and 42CrMo4. Strong, tough and easy to heat treat.
EN19
A widely used chrome-moly steel with good hardenability, toughness and fatigue strength in the quenched and tempered condition.
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.
42CrMo4
The EN 10083 designation of the 4140 / EN19 family, widely specified for European and export orders.
Choosing the billet
Billets are suitable for forging and upsetting into bolt and stud blanks. State the grade and the strength class so the right chemistry can be chosen.
Check the billet size chart for sections and weight per metre, and use the weight calculator for any length.
