About the material
Hardenable free-cutting steels without lead combine two properties otherwise rarely seen in combination:
- Good machinability, as seen in classic free-cutting steels
- And at the same time heat treatability for increased hardness and wear resistance
These steels are particularly suitable for applications where precision, mechanical strength and fine machining are paramount – for example in precision mechanics, watchmaking, sensor technology or the manufacture of measuring instruments.
Finemac
A hardenable free-cutting steel without lead, specially developed for precision components with the tightest tolerances.
Thanks to its finely tuned alloy composition, it can be easily machined as well as heat-treated to achieve higher degrees of hardness.
- Pb-free
- Well suited for surface hardening or case hardening
- Ideal for: small technical parts, measuring tips, filigree components
LAW 100X (1.1268 X / similar to SAE 1095)
Based on a high-carbon tool steel, this material offers outstanding hardness values after heat treatment combined with sufficient machinability.
Carbon content: approx. 1%
- Can be hardened to high strengths (> 60 HRC)
- Pb-free, but still easy to work thanks to optimised microstructure
Fields of application include:
- Precision axles
- Small springs
- Precision engineering functional parts
Advantages of hardenable free-cutting steels without lead
- Lead-free: meets environmental standards and norms (RoHS-compliant)
- Machinability: improved working despite lack of added Pb
- Hardenability: suitable for thermal hardening processes (e.g. oil bath)
- Suitable for precision engineering: ideal for the smallest parts with high shaping accuracy
