Overview of Working with HARDOX
HARDOX can be welded, bent, cut and
machined using run-of-the-mill
techniques and tools. You get the
superior performance of HARDOX
without having to invest in special
equipment and training.
Preheating
The right preheat and interpass
temperature for each welding
situation will optimize the result.
Welding
Any conventional welding method can
be used for welding these steels to
any type of weldable steel.
Cutting
HARDOX wear plate can very well be
cut using both cold and thermal
cutting methods.
Bending
HARDOX is eminently well suited for
cold bending.
Machining
HARDOX can be machined with high
speed steel or cemented carbide
tools. |

Preheating HARDOX
The right preheat and interpass
temperature is important in order to
avoid hydrogen cracking. The right
preheat and interpass temperature is
important in order to avoid hydrogen
cracking.
A unique combination of alloying
elements optimizes the mechanical
properties of Hardox. This
combination governs the preheat and
interpass temperature of the steel
during welding, and can be used to
calculate the carbon equivalent
value. |

Welding HARDOX
Any conventional welding method can
be used for welding these steels to
any type of weldable steel. The
information pdf file in the summary
column is aimed at simplifying,
improving and boosting the
efficiency of the welding process.
It offers good advice on preheat and
interpass temperatures, heat input,
welding consumables, shielding gas
and a great deal more. We want every
user to take advantage of the full
benefits of the unique properties of
Hardox. |

Cutting HARDOX
Gas cutting of HARDOX plate is easy.
As in all thermal cutting, a
heat-affected zone occurs at the cut
surface. Thick HARDOX 400/450/500
should be preheated before gas
cutting.
For producing smaller parts or to
minimize hardness reduction in the
zone adjacent to the cut surface,
abrasive water-jet cutting or laser
cutting may be good alternatives to
gas cutting. In abrasive water-jet
cutting, which is a cold- working
process, the material will lose none
of its hardness. In laser cutting,
the heat-affected zone is very
small. |

Press & Roll Bending HARDOX
Purity, flatness and consistent
quality make HARDOX plate well
suited for press and roll bending.
The pdf file in the summary column
shows examples of recommended
minimum values for free bending of
plate of different thicknesses and
with different die openings.
As a general rule, thinner plate can
be bent to smaller radius. The plate
can be bent to a smaller radius
transverse to the direction of
rolling than in the direction of
rolling. |

Machining HARDOX
HARDOX 400, HARDOX 450 and HARDOX
500 can be machined in all machine
tools, using tools with index able
inserts and in a stable, vibration-
free set-up.
HARDOX plate can also be machined in
a stable radial drilling machine.
Rigid HSS-Co drills must be used for
drilling. Using appropriate tools,
HARDOX plate can also be spot-faced
and counterbored.
Machining of HARDOX plate may
produce long chips, particularly in
turning. This is due to the high
purity of the plate. |
