| Item | Reference / purchasing detail |
|---|---|
| Material/product | 12L14 Leaded Steel Round Bar |
| Grade identity and purchase standard | SAE/AISI 12L14; verify applicable carbon steel purchasing standard |
| Delivery or treatment condition | Cold-drawn or other specified bar condition; lead content must be certified |
| Typical applications | High-volume fittings, bushings, machined fasteners and terminals |
| Selection concern | Intentional lead additions affect recycling, use restrictions and welding decisions; do not describe 12L14 as lead-free. |
| Mozaic processing | Precision round-bar grinding, straightening, cutting, chamfering and packing when feasible |
Technical overview, not a certified composition or mechanical-property report. Confirm grade designation, product standard, required condition and heat-lot documentation for every order.
Why Material Grade and Condition Matter
Intentional lead additions affect recycling, use restrictions and welding decisions; do not describe 12L14 as lead-free. Representative components include high-volume fittings, bushings, machined fasteners and terminals. Different grades can share a broad alloy family while requiring distinct finishing, inspection or material qualification. Procurement and engineering should agree on the supplied condition and part performance before accepting substitutions.
Precision Bar Supply and Processing
Mozaic Precision Metals offers project-specific centerless grinding, bar straightening, polishing, saw cutting, chamfering and packaging. Our quoting process considers material condition, diameter, length and the required final surface. Diameter tolerance, straightness and roughness should be specified and inspected separately.
