Case Hardening Steel

Case Hardening Steel

A tough core and a hard case are the desired attributes of case-hardened steel components. This combination of properties provides wear resistance and fatigue strength at the surface, and impact strength in the core. It is achieved by carburizing the component’s surface, then quenching and tempering the part. Carburized components include gears of all kind, camshafts, universal joints, driving pinions, link components, axles and arbours. All these components must resist wear and fatigue, have inherent toughness, and still be machinable.

Typical Application Include

• Transportation: Case-hardened components are needed in any engine-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 include 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.
