CASE-HARDENING STEELS

Case-hardening steels are employed for manufacturing mechanical pieces that have to be highly hardened on the surface with a carburizing heat treatment process followed by martensitic hardening and stress- relieving tempering.
As a result, a hard surface layer with a softer, tough and resistant core can be obtained. These steel grades can be used, for example, for the construction of shafts and gears.
