Welded steel chains (WSC)
“narrow” series WR/WH/WHX
The KettenWulf “narrow” series of welded chains is
widely used for transport applications in the timber
and bulk material handling industries as well as in
other areas with high stress on the chains. The narrow
series is available in three versions. Their designations
reflect the heat treatment used for producing
their components.
WR series:
The pins of the KettenWulf WR series are through
hardened to ensure optimal wear resistance. Link
plates and bushes are untreated.
WH series:
All components of the KettenWulf WH series are fully
heat treated. This improves the chains wear resistance
and increases its breaking load and fatigue
strength.
WHX series:
Certain parts of the pins of the WHX series are induction
hardened in addition to the general treatment.
The high strength induction-hardened section ensures
maximum wear resistance while the tempered
section ensures that the pin retains its optimal toughness
and shock resistance. The link plates and bushes
of this chain are heat-treated just like the components
of the WH series.
