Case-hardening steel normally has a carbon content of up to 0.25% and this relatively low carbon content makes it an inherently tough material. Using the case-hardening technique, a carbon content of 0.65% to 0.9% is infused into the surface layer during the carburization phase of the casting process. By controlling the time at temperature and the carbon level, the depth to which the carbon diffuses can be controlled, and thus the ratio of ''case'' to ''core'' can be adjusted to suit any requirement.


Typical applications of these steels include


Transportation: Case-hardened components are needed in any engide-driven vehicle, whether it's a small car, a racecar, a truck or an ocean vessel.


Energy generation: Gear wheels and large components have to withstand cyclic stress and wear in hydroelectric power stations, wind-turbine generators, propeller drives of drilling rigs and steam-turbine gears of power stations.


General mechanical engineering: General mechanical engineering: Applications in this area iclude forging presses, metal rolling equipment, machine tools; drivelines of mining equipment and heavy-duty transmissions; earthmoving equipment and heavy-duty construction cranes. Wear resistance and good fatigue strength are always key characteristics of the case-hardened steels used for these applications.


In CEL-MER we are specialized on the hot and cold forming of case hardening steels in different grade / size combinations.
