4145 Round Bar: Material Profile
4145 provides more hardness potential than lower-carbon 41XX grades while retaining alloy toughness and hardenability.
Orders typically state a heat-treated condition and mechanical-property range.
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
- High strength potential
- Good hardenability
- Wear resistance
- Good fatigue performance
Common Applications
- Heavy-duty shafts
- Oilfield components
- Gears and couplings
- High-load machinery parts
Specification Requirements
Identify the governing specification and revision, product form, section size, condition, mechanical properties, testing, and certification requirements. The purchase specification and material certification govern the order.
