Quenched and tempered steels
Quenched and tempered steels are common in mechanical engineering. Thanks to their hardness and resilience, they are suitable for a wide range of applications. Quenched and tempered steels are also well suited for surface tempering that improves the durability of the piece.
We stock quenched and tempered steels in two steel grades: 42CrMoS4+QT and 25CrMoS4+QT. In order to ensure good machining qualities, the sulfur content of the products has a lower limit.

Cast iron bars
Grey cast iron GJL-250C has excellent machining characteristics, and it is used in machine parts that are subject to lighter loads. The mechanical characteristics of spheroidal graphite cast iron GJS-500-7 are even better than those of simple mechanical steel grades. Its notch toughness, fatigue resistance and wear resistance are better than grey cast iron’s. Cast iron ahs excellent vibrodamping properties. We deliver cast iron bars without heat treatment.
