4820 Round Bar: Material Profile
4820 combines a carburizable carbon level with substantial nickel for core toughness in highly loaded components.
Purchasing requirements should define section size, quality restrictions, case and core properties, and the heat-treated condition.
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
- Excellent toughness
- Good carburizing response
- Good fatigue resistance
- Strong shock-load performance
Common Applications
- Heavy-duty gears
- Drive shafts and pinions
- Aircraft power-transmission parts
- Case-hardened industrial components
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.
