Case-hardened steels

Case-hardening steels are steels with a low carbon content of 0.10 to 0.20 %. The carbon content in the surface layer can be increased by case-hardening the material. This way, the core retains the toughness and breaking strength of the steel, but the surface is hardened and as such, it has a high resistance to wear. Case-hardened steels are therefore used for components that are exposed to high mechanical loads. These include, for example, gears, gear wheels, shafts and bolts.

By adding alloying elements such as manganese or chromium, the core strength and wear resistance can be optimised for various applications.

Wilhelm Jungermann GmbH supplies case-hardening steels in various designs, shapes and dimensions for wear-resistant components with high dynamic loads.

Properties of case-hardening steel

  • Alloyed or low alloyed
  • Lower carbon content in the core
  • Higher carbon content in the surface layer
  • Case-hardening by carburising/carbonitriding
  • Resistant to wear
  • Not rust free

Applications of case-hardening steel

  • Gears
  • Rack-wheels
  • Chains
  • Bolts
