DIN1.2842 Cold Worked Tool Steel
Unmatched Edge Retention
DIN 1.2842’s high carbon and chromium content ensures superior edge sharpness and wear resistance, making it ideal for precision cutting tools like thread-rolling dies and shear blades. Its hardness (>61 HRC) outperforms many conventional cold work steels.
Minimal Distortion & High Machinability
The steel’s low annealing hardness (<229 HB) allows for easy machining and polishing. Its oil-hardening process minimizes warping, critical for tools requiring tight tolerances, such as measurement plates and mold inserts.
Versatile Industrial Adaptability
From paper-cutting blades to high-stress fixtures, DIN 1.2842 adapts to diverse applications. Its thermal stability (53 HRC at 400°C) ensures reliable performance in moderate high-temperature environments, reducing downtime and maintenance costs.
