In general, design of abrasion resistant steel is based on the assumption that abrasion resistance increases
with hardness. However, in practical use, some problems are created with an increase in hardness exceeding
500 HB. Therefore, abrasion resistant steels should have a combination of high abrasion resistance, good
cold formability and sufficient impact toughness. Relia® is ArcelorMittal’s new range of high hardness,
low-alloyed martensitic steels, offering outstanding resistance to wear and abrasion. Despite their extreme
hardness, the properties of Relia® plates are specifically designed for improved workability such as cutting,
forming, drilling and welding to realise any kind of applications and designs.
