4615 Round Bar: Material Profile
4615 is intended for case-hardened components where nickel supports toughness and molybdenum improves hardenability.
Include the required case depth, surface hardness, core properties, bar condition, and governing material specification.
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 case-hardening response
- Tough core
- Good fatigue resistance
- Machinable before carburizing
Common Applications
- Gears and pinions
- Bushings and sleeves
- Small shafts
- Case-hardened transmission 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.
Request Pricing for 4615 Round Bar
We quote 4615 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.
