Quenched and tempered steels and case-hardened steels for special heat treatment processes in accordance with DIN EN 10083-2, DIN EN 10084 and DIN EN 10132-2
Quenched and tempered steels and case-hardened steels are among the most versatile material groups in the metal industry and are used for mechanical components subject to high stresses due to their high strength and wear resistance. The DIN EN 10083-2 standard defines the chemical composition and properties of unalloyed quenched and tempered steels in order to meet the requirements for components such as shafts, bolts and gears. Case-hardening steels according to DIN EN 10084 are characterized by a hard surface layer and a tough core, which makes them particularly suitable for components with high surface loads such as gears and shafts. Cold-rolled steel strip for heat treatment, which falls under DIN EN 10132-2, is used particularly in precision applications where a fine microstructure and high surface quality are required.
Heat treatment conditions and their significance
The specific heat treatment is decisive for the desired mechanical properties of these steels. The DIN standards specify various heat treatment conditions in order to optimally adapt the usability and properties of the steel to the requirements of the applications.
Areas of use and variety of applications
The various standards and heat treatment processes ensure that the materials meet the specific requirements of industrial practice. Unalloyed quenched and tempered steels in accordance with DIN EN 10083-2 are used in structural parts such as drive shafts and gear wheels that have to withstand mechanical loads. Case-hardening steels in accordance with DIN EN 10084 offer an ideal combination for components that require a high surface hardness thanks to their hard surface layers and tough cores. Finally, cold-rolled strip in accordance with DIN EN 10132-2, which is optimized for heat treatment, ensures a fine microstructure and excellent surface quality that is suitable for precise applications.
Strict compliance with DIN standards ensures that material quality is controlled and optimized so that the end products are reliable and durable.
