| Composition | Contains sulfur (S) and lead (Pb) to enhance machinability |
| Surface Finish | Provides excellent smoothness during high-speed cuts |
| Tool Life | Reduces wear on tools even in continuous turning environments |
| Chip Control | Produces short, manageable chips for safe and clean operations |
| Dimensional Stability | Maintains tolerances under rapid machining cycles |
Mechanical Properties Overview
| Property | Typical Value |
|---|---|
| Tensile Strength | 440–580 MPa |
| Yield Strength | ~280 MPa |
| Elongation | ~22% |
| Hardness | ~160 HB |
| Machinability | Excellent (over 100%) |

Why It’s Better for High-Speed Use
Unlike standard carbon steel, 11SMnPb30 produces less heat during cutting, allowing for faster tool speeds without compromising quality. Its enhanced lubricity from lead content also helps maintain tool sharpness and dimensional accuracy.If you’re operating high-speed CNC lathes and need consistent, cost-effective results, 11SMnPb30 is an excellent choice. It reduces tool change downtime, improves surface finishes, and keeps your production lines running smoothly.
