Relia® is ArcelorMittal’s range of high hardness, 400-450 and 500 HBW low-alloyed martensitic steels, offering outstanding resistance to wear and abrasion.


Relia® extends the service life of wear parts and machinery components:

  • Lower maintenance costs
  • Greater payload capacity
  • Lighter weight
  • Extended maintenance cycles


  • Thermal cutting
    Relia® sheets & plates are compatible with all thermal cutting processes including oxy-fuel, plasma, and laser

  • Cold formability
    Thanks to their high cleanliness and uniform properties, Relia® Premium plates are specifically designed for improved formability in particular when subsequent cold forming is required.

  • Welding
    Due to its low carbon content and low carbon equivalent value, Relia® exhibits very good welding characteristics using any conventional fusion welding methods.


Relia® wear-resistant steels can be used in a wide range of applications:

  • Construction, public works and road transportation
  • Excavation, hauling and bulk material handling for mining, quarrying, and mineral industries
  • Raw mineral processing includes a large number of technologies for comminution and sizing
  • Heavy duty demolition equipment, waste, and recycling machinery
