- Excellent carburizing response
- Good core toughness
- Good fatigue resistance
- Good impact performance
Common Applications
- Gears and pinions
- Shafts and arbors
- Bearings and races
- Heavy-duty 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 8720 Round Bar
We quote 8720 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.
