41L40 Round Bar: Material Profile
41L40 retains the general strength and heat-treatment capability associated with 4140 while lead additions improve chip control and tool life.
Its use should be checked against welding, elevated-temperature, regulatory, and end-customer restrictions before 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
- Improved alloy-steel machinability
- Good hardenability
- High strength potential
- Good wear resistance
Common Applications
- Machined shafts
- Hydraulic components
- Couplings and fittings
- High-volume alloy-steel 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 41L40 Round Bar
We quote 41L40 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.
