Amstrong^® Ultra

Amstrong^® Ultra is ArcelorMittal’s range of ultra high strength structural steels developed for demanding applications where weight reduction, high fatigue resistance and structural integrity are critical.

With minimum yield strengths from 650 to 960 MPa, Amstrong^® Ultra enables manufacturers to design lighter, stronger and longer components — without compromising on safety or reliability.
It is particularly suited to mobile equipment, cranes, trailers, and agricultural or mechanical machinery that must withstand dynamic loads and repetitive stress.

Produced in Europe and available in coils and sheets, Amstrong^® Ultra supports advanced structural design while ensuring ease of processing.
