Quenched and tempered round steel chains have a wide range of applications:
They are used as sling chains or in hoisting equipment, in drive technology, or in underground mining conveyor systems. These chains are each subjected to typical loads and must therefore exhibit certain mechanical properties. High tensile strength and toughness are particularly important here. These properties can be improved and optimized through appropriate heat treatment. In addition to quenched and tempered chains with uniform hardness throughout their cross-section, case-hardened chains are also used. These have a higher surface hardness, which, however, decreases sharply toward the core. Accordingly, their properties and applications also differ:
If high wear resistance is required, case-hardened chains are used; if high toughness and breaking strength are needed, quenched and tempered chains are employed.

Induction heat treatment is used to produce round steel chains with a very high tensile strength for applications such as lifting chains. The entire heat treatment process can be carried out on a single system. The advantages of induction heating—such as energy efficiency, speed, and good reproducibility—can be leveraged.
Systems are tailored to the range of parts and configured according to the customer’s requirements and preferences.
