Standard steels
A complete range of carbon and alloy steels meeting national and international standards.
- Through-hardening steels (Cr, Cr Mo, Ni Cr Mo, B)
- Case-hardening steels (16MnCr5 to 30CrMoV9)
- Bearing steels (C55, C70, 100Cr6...)
- Spring steels (55Cr3 to 52SiCrNi5)
- Surface-hardening steels
- Steels for fasteners
- Steels for nitriding, carbonitriding (34CrAlMo5 to 40CrAlMo6-12Pb)
- Micro-alloy steels (38MnSiV5 to 22MnV7)
- Non alloyed steel (C15 – C55)
- Steel with Sulfur, and/or Lead...
