4130 Round Bar: Material Profile
4130 is used for structural and mechanical components where strength without excessive weight matters.
Supply condition, welding procedure, heat treatment, and mechanical properties must match the governing 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 strength and toughness
- Responsive to heat treatment
- Good fatigue resistance
- Good fabrication range
Common Applications
- Shafts and structural parts
- Aircraft and transportation components
- Roll cages and frames
- Oilfield and 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.
Request Pricing for 4130 Round Bar
We quote 4130 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.
