Certified Hardox® Wearparts center
OMNIS is part of the global network of centers certified by the Swedish steelmaker SSAB, and one of only two such centers in Serbia. We have been in the network for more than nine years.
What certification means
The material is only half the job
Hardox® is wear-resistant steel, hard from the surface through to the core. But that hardness is easily destroyed by poor processing. Cut the plate too roughly or weld with too much heat input and the material softens in the heat-affected zone — and the tool cracks exactly where the load is highest.
Certification means SSAB checks where our material comes from and how we work it. Cutting, bending, drilling and welding follow their procedures, with the specified preheating and controlled heat input. That is the difference between a tool that lasts and a tool that is merely made from more expensive plate.

Hardness grades
Harder is not always better
The right grade depends on what the machine actually digs. Too much hardness makes the tool expensive without any gain; too little and it is worn out within months. That is why we ask about the material before quoting.
Solving wear problems
We come to site
and measure the wear
Inspection in service
We look at where the tool is wearing, how fast and why. It often turns out the problem is not the material but the geometry — the wrong cutting angle, or too little protection between the teeth.
Remaining life assessment
We measure the remaining thickness at the critical points and estimate how many working hours are left. You then plan the replacement instead of being caught out by downtime.
Design proposal
If a tool keeps failing in the same place, we do not repeat the mistake. We propose a design change, additional armouring, or a different steel grade at that point.
Repair or replace
Repair is often cheaper than a new bucket. We carry it out in the workshop or at your location, with HARDOX® reinforcement and new edges and teeth.
Wear costs more than you think
Let us work out your cost per hour
A tool that costs more but lasts three times longer is cheaper than three cheap ones. Send us your current wear figures and we will do the arithmetic.
