X components ®
We offer processed parts and finished components
for applications that expose the materials to extremely
high stresses. These so-called X components ® are
first choice for cranes, dump bodies, buckets, tubes,
side walls and cutter bars.
On request we can also manufacture custom
X components ® from wear-resistant XAR ® steels and
ultrahigh-strength N-A-XTRA ® and XABO ® grades
from ThyssenKrupp to guarantee the best possible
quality.
