1045 Round Bar: Material Profile
1045 round bar is used where greater strength and hardness are required than lower-carbon grades typically provide.
It can be supplied in hot-rolled or cold-finished condition and is well suited to forging, machining, and induction-hardening applications.
Purchase to the controlling ASTM, SAE, AMS, or customer specification. Section size, supply condition, mechanical properties, surface limits, testing, and heat/lot traceability can change the acceptable material and processing route.
Key Characteristics
- Good strength-to-weight ratio
- Responsive to heat treatment
- Good wear resistance
- Balanced machinability
Common Applications
- Gears and sprockets
- Hydraulic cylinder shafts
- Axles and pins
- Forged machine components
