Our full range of heat-treatable steel grades consists of the Steel grades 42CrMo4, C45 and C60, which are particularly in demand in the mechanical engineering sector. The main feature of these Steel grades results from “quenching and tempering”. This describes the characteristic mechanical properties that are achieved through the ratio of toughness to strength.

Quenching and tempering is a two-stage heat treatment consisting of hardening and subsequent quenching. Quenched and tempered steel grades are unalloyed or alloyed structural steel grades that are suitable for quenching and tempering due to their chemical analysis. The basic requirement is a carbon content of between 0.20 and max. 0.60 % and special alloying elements (chromium, manganese, molybdenum and nickel). The hardness is essentially influenced by the carbon content, while the alloying elements define other Steel grades properties.
The steel normalized ex works is usually subjected to quenching and tempering in a machined state – for example as a flame-cut part. This gives the steel a high level of hardness and strength. Subsequent tempering slightly reduces the hardness but significantly increases the toughness.
Components made of heat-treated steel are used in machine components such as axles, shafts, screws and other structural elements.
The advantage of working with our company is that we can supply you with both flame-cut parts and machined parts ready for assembly.
