4620 Round Bar: Material Profile
4620 provides greater core carbon than 4615 while maintaining the case-hardening and toughness benefits of the 46XX family.
The intended section size, carburizing practice, case requirements, and final mechanical properties guide supply selection.
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 carburizing response
- Good core toughness
- Good hardenability
- Good impact resistance
Common Applications
- Transmission gears
- Pinions and shafts
- Heavy-duty bushings
- Powertrain 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.
Request Pricing for 4620 Round Bar
We quote 4620 for manufacturers and commercial buyers. Requirements of 3,000–10,000 lb are welcome, along with multi-ton and truckload programs.
We are not a retail metal store. Small personal-use, typical single-bar, and cut-piece orders are generally not a fit. The material field is prefilled and remains editable; add the specification, size, condition, total weight, processing, testing, required date, and ship-to location.
