Hot-rolled carbon steels for heat treatment

Roller chains made of carbon steel

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.

Our carbon steel portfolio

Case-hardening steel

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.

Product details

Unalloyed and alloyed quenched and tempered steel

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.

Product details

Spring steel

Spring steels are within the carbon range of 0.55 to 1.00%. We deliver spring steels based on DIN EN 10132-4.

Product details

Hardenable manganese-boron steel

We deliver manganese-boron alloyed tempering steels based on DIN EN ISO 683-2 (previously DIN EN 10083-3) as well as our special mill grades tubor® – optimized MnB steels for precision steel tubes.

Product details

Hardenable boron steel TBL

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.
