Unalloyed and alloyed carbon steels from thyssenkrupp are intended for heat treatment, in which important properties such as hardness, wear resistance and toughness are controlled.
A distinction is made between case-hardening steels, unalloyed and alloyed heat-treatable steels and spring steels. Carbon steels are suitable for high static and dynamic loads.Typical applications for C-steels are shafts, gear parts, stabilizers, roller chains, springs, saw blades and seat adjuster units.
Heat treatment of carbon steels
In heat treatment a fundamental distinction can be made between the hardening and tempering processes. Hardening comprises the heating and quenching of a workpiece in order to increase its hardness and strength. In tempering, the quenched and hardened workpiece is reheated in order to adjust the optimal hardness and toughness properties.
Case-hardening steels are mostly within the carbon range of 0.10 to 0.30%. They are intended for case hardening. We deliver case-hardening steels based on DIN EN ISO 683-3 (previously DIN EN 10084) und DIN EN 10132-2.
Quenched and tempered steels are mostly within the carbon range of 0.20 to 0.60%. We deliver unalloyed QT steels based on DIN EN ISO 683-1 (previously DIN EN 10083-3) and DIN EN 10132-2 as well as alloyed quenched and tempered steels based on DIN EN ISO 683-2 (previously DIN EN 10083-1, DIN EN 10083-3) and DIN EN 10132-3.
Our fine-grain boron alloyed heat-treatable steel (analytically according to DIN EN ISO 683-2, previously DIN EN 10083-3) for agricultural machinery with excellent processing properties and wear resistance.
