Case hardening process used to
increase wear resistance, surface hardness and fatigue life through creation of
a hardened surface layer while maintaining an unaffected core micro structure.
Induction hardening in Faridabad is
used to increase the mechanical properties of ferrous components in a specific
area. Typical applications are power train, suspension, engine components and
stampings. Induction hardening is excellent at repairing warranty claims / field
failures. The primary benefits are improvements in strength, fatigue and wear
resistance in a localized area without having to redesign the component.
Benefits
Induction imparts a high surface
hardness with a deep case capable of handling extremely high loads. Fatigue
strength is increased by the development of a soft core surrounded by an
extremely tough outer layer. These properties are desirable for parts that
experience tensional loading and surfaces that experience impact forces.
Induction processing is performed one part at a time allowing for very
predictable dimensional movement from part to part.
Application & materials
Induction hardening is a heat
treatment process carried out to enhance the mechanical properties in a localized
area of a ferrous component. The resultant hardened area improves the wear and
fatigue resistances along with strength characteristics.
Typical applications of induction
hardening include gears, shafts, axles, cam lobes, and stampings, and spindles,
mostly symmetrical parts. Induction
hardening is used to strengthen a specific area of a part.

Process details
Induction hardening is a process
used for the surface hardening of steel and other alloy components. The parts
to be heat treated are placed inside a copper coil and then heated above their
transformation temperature by applying an alternating current to the coil. The
alternating current in the coil induces an alternating magnetic field within
the work piece which causes the outer surface of the part to heat to a
temperature above the transformation range.
The components are heated by
means of an alternating magnetic field to a temperature within or above the
transformation range followed by immediate quenching. It is an electromagnetic
process using a copper inductor coil, which is fed a current at a specific
frequency and power level case
