Cutting of HARDOX wear plate
Oxygen fuel cutting of HARDOX wear plate
is as simple as cutting of regular Mild Steel.
When cutting of thicker HARDOX plates special
attention is needed. For thick and hard plates the
risk of developing cut edge cracks increases. By
following the recommendations and guidelines
given below cut edge cracking and component
softening can be prevented.
Cutting methods
HARDOX wear plate can very well be cut
using both cold and thermal cutting methods.
The cold methods are abrasive water jet cut-
ting, shearing, sawing or abrasive grinding,
while thermal methods are oxy-fuel, plasma
and laser cutting.
