Case Hardening steel
Steels designed for the hardening of the surface layer
Carburized steels, with a low carbon content, allow pieces to be obtained that, after the mechanical processing and carburizing treatment, combine a high surface hardness with a good core toughness.
Thanks to the high surface hardness that can be obtained with the carburizing treatment, these steels are used to create those mechanical bodies for which a considerable surface hardness is necessary, such as gears, pins, bushes, shafts, and everything necessary for the transmission of motion.
The versatility of the range of carburized steels allows a vast range of uses to be covered, from the smallest gears to motor shafts of considerable size.
The heat treatments available for this type of steel – to be checked on a case-by-case basis according to the different qualities – are: rolled natural, workable annealed, isothermal annealed, globular annealed, normalized, and quenched and tempered.
