Tight-Tolerance Ultra-Machinable 12L14 Carbon Steel Rods
- Yield Strength: 65,000 psi
- Hardness: Rockwell B80 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C65
- Fabrication: Cold Worked
- Specifications Met: ASTM A108
Ready for turning in a lathe, these rods are precision ground and held to a strict straightness tolerance. The lead additive acts as a lubricant, which allows 12L14 carbon steel to withstand very fast machining. It's used to fabricate a wide variety of machine parts, such as shaft couplings, studs, and pins. These rods meet ASTM A108 quality and performance standards. For added wear resistance, they can be surface hardened with heat treating.
Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
